Question

Peggy has twice as many apples as kiwis, and three times as many pears as apples. How many pears does she have, if she has 72 apples, kiwis and pears all together?

Answer 1

$a = 2k\\\\p = 3a\\\\a+p+k = 72\\\\\dfrac{p}{3}+p+\dfrac{p}{6}=72\\\\\dfrac{4p+12p+2p}{12}=72\\\\\dfrac{18p}{12}=72\\\\\dfrac{3p}{2}=72\\\\p=48$

Answer 2

Answer:

Let's do this step by step

Since there are 72 apples, the pears are 3 times as much. So multiply by 3

$72 * 3=216$

So there would be 216 pears.

Now for Kiwis

They are 2 times as much, Multiply by 2

$72 *2=144$

All together with the kiwi and the pears are

$216+144=360$

And all the fruits together it would be

432

Hope this helps
