Question

There are 3 3/4 pounds of bricks in a bag. Each brick weighs 5/8 of a pound. How many bricks are in the bag.

Answer 1

Answer: There are 6 bricks in the bag.

Explanation:

Convert from mixed number to decimal number. To do it, divide the numerator of the fraction by the denominator and add the result to the whole number part. Then:

`3(3)/(4)\ lb=(3+0.75)\ lb=3.75\ lb`

Convert from fraction to decimal number. To do it you need to divide the numerator by the denominator. Then, you get:

`(5)/(8)lb=0.625\ lb`

Let be "x" the number of bricks in the bag.

Based on the information given in the exercise, you can set up the following proportion:

`(1)/(0.625)=(x)/(3.75)`

Finally, you must solve for "x" in order to find its value. This is:

`(3.75)((1)/(0.625))=x\\\\x=6`
