Answer: There are 6 bricks in the bag.
Step-by-step 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:
[tex]3\frac{3}{4}\ lb=(3+0.75)\ lb=3.75\ lb[/tex]
Convert from fraction to decimal number. To do it you need to divide the numerator by the denominator. Then, you get:
[tex]\frac{5}{8}lb=0.625\ lb[/tex]
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:
[tex]\frac{1}{0.625}=\frac{x}{3.75}[/tex]
Finally, you must solve for "x" in order to find its value. This is:
[tex](3.75)(\frac{1}{0.625})=x\\\\x=6[/tex]
