Mom 6

Mom is throwing a party and buying cakes. Twice as many cakes for each adult as for each child.
1. What proportion of the cakes are for children if the number of adults at the party is twice as many as the number of children?
2. What proportion of the party participants are adults if half of all the cakes that Mom bought are for children?

Final Answer:

a =  1/5
b =  1/3

Step-by-step explanation:

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

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