The ratio of girls to boys in a certain school is 85. if the school has 221 students how many are boys?
To find the number of boys in the school, we first need to determine the total number of parts in the ratio, which is 85 (girls) + 1 (boys) = 86 parts. Then, we divide the total number of students by the total parts in the ratio: 221 students / 86 parts = 2.57 students per part. Since we can't have a fraction of a student, we round down to the nearest whole number, which means there are 2 boys in the school.
How many students in a class of 108 students are girls if the ratio of girls to boys is 5 to 4?
Well, isn't that a happy little math problem! If the ratio of girls to boys is 5 to 4, that means for every 5 girls, there are 4 boys. To find out how many girls in a class of 108 students, we first need to divide 108 by the total parts in the ratio (5+4=9), which is 12. Then, we multiply 108 by the girls' share (5/9) to find there are 60 girls in the class.
What angle is made by the hands of the clock at four o'clock?
120 degrees is the angle made by the hands of a clock at 4 o clock. To get this answer, you could divide the clock into equal parts (12), and find the ratio of the time in terms of parts to the total number of parts of the clock (which would be 4/12 in this case). Then, you cross multiply the ratio you got, to the ratio of the unknown degrees to the total number of degrees in a circle (x/360). (4 * 360 = 12x). The answer should be 120 degrees.
If there is a 3 to 7 ratio of boys to girls how many boys are there?
If the ratio of boys to girls is 3:7, this means that for every 3 boys, there are 7 girls. To find out how many boys there are, you would need to divide the total number of children by the sum of the parts in the ratio (3 + 7 = 10) and then multiply that result by the number of boys' parts in the ratio (3). So, if there are 30 children in total, there would be 9 boys (30 divided by 10, times 3).
How can you find the total number in a whole given the percent and the number of parts?
====== Answer 1: ----------- proportion... A portion of the total is to its percentage of the total as the total is to 100%.
If the ratio of boys to girls in a class is 5 to 8 and there are 40 girls how many boys are in the class?
To find the number of boys in the class, we first need to determine the total number of students. Since the ratio of boys to girls is 5 to 8, the total parts of the ratio is 5 + 8 = 13. If there are 40 girls in the class, we can calculate the total number of students as 40 girls / 8 girls per part = 5 parts. So, the total number of students is 5 parts * 13 total parts = 65 students. To find the number of boys, we can calculate 65 total students - 40 girls = 25 boys in the class.

How do yo do ratio maths?
To share in a given ratio 1) Simplyfy the given ratio by putting each part of the ratio over the LCD 2) find the total no. of parts (add up the simplified ratio) 3) no. of parts / total no. of parts x total amount to be shared = the amout each person reacieves
The ratio of yes votes to no votes in an election was 5 to 6 How many yes votes were cast if there were a total of 6281 votes cast?
To find the number of yes votes, we first need to calculate the total parts in the ratio, which is 5 + 6 = 11. Then, we divide the total number of votes by the total parts in the ratio: 6281 / 11 = 571. Next, we multiply this result by the number of parts representing yes votes (5) to find the number of yes votes: 571 * 5 = 2855. Therefore, there were 2855 yes votes cast in the election.
Divide 100 pounds into three parts in the ratio 10 13 2?
Total number of parts is 25 therefore each part is 4 pounds, so your answer is 40, 52 and 8.
A number used to multiply both parts of a ratio to be equal?
That is necessary if trying to find an equivalent ratio: not otherwise.
What does 5 to 3 ratio mean to get 120000?
A 5 to 3 ratio means that for every 5 parts of one quantity, there are 3 parts of another quantity. To find how many parts there are in total, you add the two parts together: 5 + 3 = 8 parts. To find the value of each part, you divide the total value (120,000) by the total number of parts (8): 120,000 / 8 = 15,000. Therefore, in a 5 to 3 ratio to get 120,000, each part would be equal to 15,000.

What is the ratio of the number of equally likely outcomes in an event to the total number of possible outcomes?
You find the total number of outcomes by adding the first part of the odds to the second part of the odds. For example: 1:1 The total number of outcomes would be 2. To find the ratio of equally likely outcomes to the total number, find the number of outcomes, and put it on the left of the semicolon. Then put the total number on the right side. For the same example: (outcomes)->1:2<-(total)
What is 650 to the ratio of 5 and 8?
To find 650 in the ratio of 5:8, you first need to add the parts of the ratio (5+8=13). Then, you divide 650 by the total parts of the ratio (650/13=50). Finally, you multiply this result by the individual parts of the ratio to find the corresponding values: 550=250 and 850=400. Therefore, 650 in the ratio of 5:8 is 250:400.
