A set of encyclopedia has 27 volumes. each volume is 1 3/8 inches thick. If the volumes are placed side by side, how long will the set be?

What do you think?

I'll be glad to check your answer.

I'm not sure how to find the answer.

You have two numbers. Should you add, subtract, multiply, or divide?

Which will give you a reasonable answer?

Would you multiply

To find the total length of the set of encyclopedias, we need to multiply the number of volumes by the thickness of each volume.

First, let's convert the thickness of each volume to a fraction. 1 3/8 can be written as (8/8 + 3/8), which equals 11/8.

Now, we can calculate the total length of the set of encyclopedias by multiplying the number of volumes (27) by the thickness of each volume (11/8):

27 * 11/8 = 297/8 inches.

However, we should simplify the fraction to get a mixed number result. To simplify 297/8:

Divide 297 by 8: 297 รท 8 = 37 with a remainder of 5.

The simplified fraction is 37 5/8 inches.

Therefore, the set of encyclopedias will be 37 5/8 inches long if the volumes are placed side by side.
