Ruby ate 1/3 of a pizza angie ate 1/5 of the pizza. how much did they eat?

Ruby and Angie ate 8/15 of the pizza

You have to add 1/3 and 1/5
first, you need to find a common denominater, which, in this case is 15
Since 3 times 5 is 15, the first fraction turns into 5/15 and the second fraction turns into 3/15 3 plus 5 is is 8. so the answer would be 8/15

X= 2 he can buy 2 packs of cards for $12 and an action figure for $3 so he would spend $15 in total plus the free poster
