AysviL [449]

Answer:

Cost 0.70 per pound.

Step-by-step explanation:

If you see the cost and the weight you can get the price per pound, so if 5 pounds cost $3.50, you can evaluate doing a rule of three:

Katie had 4 full cement blocks and one that was 4⁄6 the normal size. If each full block weighed 3 2⁄4 pounds, what is the weight
sveta [45]

Answer:

The weight of the block that Katie has is 16 1/3 pounds

Step-by-step explanation:

<u>Katie has: 4 full cement blocks and 4/6 (or 2/3 ) of the normal size of a cement block</u>

For one full block, it weighs 3 2/4 ( or 1/2) pounds, if you want to find the answer of the question, you need to multiply the weight with the cement blocks that Katie have.

<u>First do the four full cement blocks:</u>

4 * 3 2/4 = ?

4 * 14/4 = ?

Cancel the 4 that is being multiplied and the 4 that is being divided by 14.

= 14.

<u>Now do the 4/6 (or 2/3) cement block:</u>

2/3 * 3 2/4 = ?

2/3 * 14/4 = ?

Multiply the fractions together:

= 28/12

= 2 1/3

<u>Finally, you add up the full blocks and the 2/3 cement block to get your answer:</u>

2 1/3 + 14 = 16 1/3

The weight of the block that Katie has is 16 1/3 pounds
