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
