Mom 6

Mum is throwing a party and buying cakes. She buys twice as many cakes per adult as per child.
1. What proportion of the cakes are for children if the number of adults at the party is twice the number of children?
2. What proportion of the party participants are adults if half of all the cakes Mum bought are for children?

Final Answer:

a =  1/5
b =  1/3

Step-by-step explanation:

$a=\frac{1}{2\cdot 2+1}=\frac{1}{5}=0.2$

$b=\frac{1}{1+2}=\frac{1}{3}=0.3333$
