Given:
Andrew has one book that is 2 3/7 inches thick and
A second book that is 3.56 inches thick
To find:
If he stacks the books, about how tall will the stack be
Solution:
Thickness of first book = 2 3/7 inches
Here 2 3/7 is mixed fraction convert into a improper fraction so that we get the thickness of book in decimal number
⇒ 2 3/7 = 17/7 [ 17 = 7×2 +3 ]
⇒ 17/7 = 2.43
Thickness of first book = 2.43 inches
If he stacks the books, the length of stack be
= thickness of 1st book + thickness of 2nd book
= 2.43 + 3.56 = 5.99 inches
The length of the stack = 5.99 inches
