Samir bought 3 pounds of cement to repair the cracks in his sidewalk. Each crack needs to be filled with 2 ounces of cement.

24 cracks will be filled

Step-by-step explanation:

Here, the first question asks how to convert 3 pounds to ounces.

we can do this using a mathematical approach. To convert pounds to ounces, we need to know that there are 16 ounces in a pound. so to convert pounds to ounces, we just need to multiply the number of pounds we have by 16 to get the equivalent number of ounces.

The second question asks to give the number of cracks that be repaired.

From the question, we were made to know that each of the cracks would eat up 2 pounds of cement to be filled.

Let’s calculate the amount of cement we have. That would be 3 * 16 = 48 ounces of cement.

The amount of cracks to be filled is thus 48 ounces/2 ounces = 24 cracks

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
