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.
Bess [88]

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:

3\frac{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:

\frac{5}{8}lb=0.625\ lb

Let be "x" the number of bricks in the bag<em>.</em>

<em> </em>Based on the information given in the exercise, you can set up the following proportion:

\frac{1}{0.625}=\frac{x}{3.75}

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

(3.75)(\frac{1}{0.625})=x\\\\x=6

How to calculate 71-5(3)-(4*4)
blondinia [14]

Answer:

40

Step-by-step explanation:

first do what is in the parentheses (4*4) which is 16 then rewrite the whole equation. 71-5(3)-16. then you'll want to multiply 5 times 3 because if there is no sign before the parentheses then it is automatically multiplication. 5 times 3 is 15. rewrite the equation again. 71-15-16 then simply subtract.

Hope this helps! :)
