Step-by-step explanation:

Givens

Given Ratio = 2/5

Given mass on earth = 140

Ratio

2/5 = x/140 or

0.4 = x / 140

Solution

2/5 = x/140                    Cross multiply

5x = 2*140                     Combine

5x = 280                       Divide by 5

x = 280/5

x = 56

You could also do this by combining the left side of the original proportion into 0.4

0.4 = x / 140               Multiply both sides by 140

0.4*140 = x                 Combine the left

56 = x
