Question

Each cement block weighs 3 3/4 pounds. How much do 4 cement blocks weigh in total?

Write your answer as a fraction or as a whole or mixed number.

pounds

Answer 1

To find the total weight of 4 cement blocks, we need to multiply the weight of one block by the number of blocks.

Each cement block weighs \( 3 \frac{3}{4} \) pounds.

First, convert \( 3 \frac{3}{4} \) into an improper fraction:

\[
3 \frac{3}{4} = \frac{3 \times 4 + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4}
\]

Now, multiply this by 4:

\[
4 \times \frac{15}{4}
\]

The \( 4 \) in the numerator and denominator cancels out:

\[
= \frac{15 \times 4}{4} = 15
\]

So, the total weight of 4 cement blocks is \( 15 \) pounds.

Thus, the answer is:

\[
15 \text{ pounds}
\]
