Question

I need help with my testAndrew has one book that is 2 3/7 inches thick and a second book that is 3.56 inches thick. If he stacks the books, about how tall will the stack be? Round to the nearest hundredth.5.93 inches5.98 inches5.99 inches6 inches

Answer 1

The first book has a thickness of 2 3/7 inches

2 3/7 in decimal is :

`2(3)/(7)=2.429`

The second book has a thickness of 3.56 inches

The height when stacked together will be the sum of their thickness. This will be :

`2.429+3.56=5.989`

Rounding to the nearest hundredth,

`5.989\sim5.99`

The answer is 5.99 inches
