75 /0.2 = 375
15 is 75% of 20
For example: 20% of 75Two methods:20 ÷ 100 × 75 = 15.20 × 75 = 15
75 50 + 20 = 5
20. Method: call the unknown number n. From the problem statement, 3n + 15 = 75, or 3n = 75 -15 = 60 and n = 60/3 = 20.

15 is 75% of 20
For example: 20% of 75Two methods:20 ÷ 100 × 75 = 15.20 × 75 = 15
You recognise that 20% is one-fifth so you multiply 75 by 5...
75 50 + 20 = 5
3 and 15/20
20. Method: call the unknown number n. From the problem statement, 3n + 15 = 75, or 3n = 75 -15 = 60 and n = 60/3 = 20.
-75%
To find the number that is 20 percent greater than 60, we can set up the equation: x - 0.20x = 60. Simplifying this equation, we get 0.80x = 60. Dividing both sides by 0.80, we find x = 75. Therefore, 75 is the number that is 20 percent greater than 60.
20% of 75 = 20% * 75 = 0.2 * 75 = 15
55 goes into 20, 4 times.5 goes into 75, 15 times.
