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.


a =  56
b =  16
p =  3.5


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
