Question

Issac's backpack weighed 75.5 ounces. If he removes one iPod that weighs 4.9 ounces and the iPad which weighs 25.6 ounces, how much does Issac's backpack now weigh?

Answer 1

First subtract the iPod weight 75.5-4.9=70.6,then subtract the IPad weight 70.6-25.6 and your final answer is 45

Answer 2

Okay so the fist thing you need to do is figure out how much the Ipod and Ipad weighs together.
Do this by adding their weights:
4.9+25.6=30.5

Now you need to subtract that from how much the total weight of the backpack was:
75.5-30.5=45

So your answer would be 45 oz.
Hope this Helps
