Divide

Divide the number 72 in the ratio 7: 2 and calculate the ratio of the numbers found in this order and write down as decimal.

Result

a =  56
b =  16
p =  3.5

Solution:

a=72⋅ 72+7=56a=72 \cdot \ \dfrac{ 7 }{ 2+7 }=56
b=72⋅ 22+7=16b=72 \cdot \ \dfrac{ 2 }{ 2+7 }=16
p=a/b=56/16=72=3.5p=a/b=56/16=\dfrac{ 7 }{ 2 }=3.5
