Question

if i have 15 tanks of fish and each tank has 20 fish and i get 15 more tanks with 20 in each how much fish do i have

Answer 1

if 15 tanks contain 20 each the total fishes in 15 tanks=15×20=300
now another 15 tanks with 20 fishes each= 15×20=300
now total=300+300
=600

Answer 2

First we had 15 tanks with 20 fish in each tank. 20 * 15 = 300
We get another 15 tanks with 20 fish each tank. 20 * 15 = 300

Add: 300 + 300 = 600
