Donuts

Find how many donuts each student will receive if you share 126 donuts in a ratio of 1:5:8

Correct answer:

a =  9
b =  45
c =  72

Step-by-step explanation:

$$\begin{gathered} x={\displaystyle \frac{126}{1+5+8}}=9 \\ a=1\cdot x=1\cdot 9=9 \end{gathered}$$

$b=5\cdot x=5\cdot 9=45$

$c=8\cdot x=8\cdot 9=72$
