Answer:
First group: 16 cookies Second group: 36 cookies
Step-by-step explanation:
First we change the ratio to a fractions. 4:9
The first ratio will have its numerator as 4 and the second one will have its numerator as 9
The denominator is the total of the variables in the ratio. i.e 4 + 9 = 13
So the first group gets 4/13 of 52 cookies
And the second group gets 9/13 of 52 cookies
You work out the of by multiplying the two numbers.
4/13 x 52 = 16
9/13 x 52 = 36
