# 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:

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