How do you find the total number of parts in a ratio?
Add them together!
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 do you use a number line to determine the ratio?
You do not use a number line to find a ratio
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.
How do you find the point that divides a line segment according to a given ratio?
-- ADD the two numbers in the ratio.-- Then divide the line segment into that many equal pieces.-- From one end, count off a number of pieces equal to either number in the ratio.-- At the point after that many pieces, the two parts of the line segment on either sideof it are in the desired ratio.

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.
How do you find the ratio of a number?
The ratio of a single number is the number itself.
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?
Since the ratio of boys to girls is 5 to 8, the total ratio parts is 5 + 8 = 13. To find how many boys are in the class, divide the total number of girls (40) by the total parts of the ratio (13), then multiply by the number of boys parts (5). Thus, there are 15 boys in the class.
How do you find the ratio of 152?
A ratio is a property of two or more numbers. It is not possible to find the ratio of a single number.

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.

How do you find the ratio of neutrons to protons?
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
How do you find the ratio?
Divide one number by the other number.
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
