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 45 are: 1, 3, 5, 9, 15, 45 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 common multiples of 20 and 25 is 100 (through 100)
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).
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
The factors of 45 are: 1, 3, 5, 9, 15, 45 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100
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".
The GCF of 15 and 27 is 3. The GCF of 15, 20 and 25 is 5. The GCF of 15, 27, 15, 20 and 25 is 1.
