You have listed the first twenty multiples of five. If there is a question here, we don't see it.
The least common multiple of the numbers 15, 20 and 25 is 300.
The factors of 75 are: 1, 3, 5, 15, 25, 75 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The prime factors of 100 are 2 and 5.The factor pairs of 100 are 1 x 100, 2 x 50, 4 x 25, 5 x 20, and 10 x 101, 2, 4, 5, 10, 20, 25, 50, 100
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The factors of 45 are 1, 3, 5, 9, 15, and 45. Factors are numbers that can be multiplied together to give the original number.
the common multiples of 20 and 25 is 100 (through 100)
20 can fit into 510 a total of 25 times. This is calculated by dividing 510 by 20, which equals 25. Since 20 multiplied by 25 equals 500, there is a remainder of 10, but 20 cannot fit into that remainder.
25% off 20 - 15 = 5 5 / 20 = 25 / 100 = 25%
All percentages begin as the number over 100. 25% is 25/100 which can be reduced to 1/4 (divide 25 and 100 by 25). So, 15% begins as 15/100 which can be reduced to 3/20 (divide both 15 and 100 by 5).
To find the percentage of boys in room 20, divide the number of boys (15) by the total number of students (25) and then multiply by 100. So, (15/25) × 100 = 60%. Therefore, 60% of the students in room 20 are boys.
The least common multiple of the numbers 15, 20 and 25 is 300.
The factors of 75 are: 1, 3, 5, 15, 25, 75 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100
100% - 75% = 25% 100% = $15 10% = $1.50 5% = $0.75 20% = $3 25% = $3.75
25% off of 20 = 15= 25% discount applied to 20= 20 - (25% * 20)= 20 - (0.25 * 20)= 20 - 5= 15
You can do this two ways; (1) First change percent to a fraction by dividing by 100. So 20% becomes .2 . Now multiply times 25 to get .2 x 25 = 5 . So 20% of 25 is 5. Now subtract that from 25 to get the new price after getting 20% off; New Price = 25 - 5 = 20. (2) Getting 20% off, means instead of paying 100% you only pay 100% - 20% = 80%. So you change 80% to a fraction, by dividing by 100, then multiply times 25 to get the new price; New Price = .8 x 25 = 20.
25% off of 20 = 15= 25% discount applied to 20= 20 - (25% * 20)= 20 - (0.25 * 20)= 20 - 5= 15
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.The prime factors of 100 are 2 and 5.The factor pairs of 100 are 1 x 100, 2 x 50, 4 x 25, 5 x 20, and 10 x 101, 2, 4, 5, 10, 20, 25, 50, 100
Twenty five percent of a number would be 1/4 of it. So that would have "25% of 80" is as "80/4 = 20".
