21 to 28

Step-by-step explanation:

Reduce each ratio to lowest terms by dividing by any common factors. (It helps to know your multiplication tables, or a quick way to find the greatest common divisor.)

15 : 20 = (5*3) : (5*4) = 3 : 4

21 : 28 = (7*3) : (7*4) = 3 : 4 . . . . same as 15 : 20

5 : 10 = (5*1) : (5*2) = 1 : 2 . . . . . ≠ 3:4

18 : 25 . . . has no common factors . . . ≠ 3:4

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
