Remember that dividing by a fraction is the same as multiplying by it's reciprocal. For example x ÷ 2/10  is the same as x * 10/2.

2÷\frac{2}{3}×-6×5÷- \frac{3}{4}
Lets convert all of the division to multiplication by using the reciprocal of the fractions
2×\frac{3}{2}×-6×5×- \frac{4}{3}
Simplify
3*-6*5*-4/3
-18*5*-4/3
-90*-4/3
120

Answer=120

Mike makes 4 dozen cookies. He brings 75% of them for a party at his school. How many did he bring?
baherus [9]

Answer:

He brought 3 dozen cookies

She ate \frac{2}{5} of the bag of Doritos

She read 25 books

Step-by-step explanation:

∵ Mike makes 4 dozen cookies

∵ He brings 75% of them for a party at his school

- Multiply 75% by 4

∵ 75% = \frac{75}{100}=\frac{3}{4}

∴ He brought = \frac{3}{4} × 4

∴ He brought = 3

He brought 3 dozen cookies

∵ Sam bought a bag of Doritos

∵ She ate only 40% of them

∵ 40% = \frac{40}{100}=\frac{2}{5}

∴ She ate = \frac{2}{5} × 1

∴ She ate = \frac{2}{5}

She ate  \frac{2}{5} of the bag of Doritos

∵ Jamie took 50 books from the library

∵ She only read half of her whole stack

- Multiply half by 50

∴ She read = \frac{1}{2} × 50

∴ She read = 25

She read 25 books

PLEASE HELP, 46 PTS!!!! ANSWER QUICKLY AND WITH FULL REPONCE AND SHOW UR WORK!!
kramer
Please limit your posts to one or two problems each.  Your demands ("show work," "answer quickly," "give a full response") should apply to YOU, not to people whom you hope will do your work for you.

<span>2. A pool company is trying out several new drains. Drain A empties a pool at a rate of 2 gal/min. Drain B empties a pool at a rate of 5 gal/min. One pool has 108 gal of water in it. Write an equation for each drain that shows the amount of time it takes to empty the pool. Then solve each equation showing your work.</span>

Drain A:  rate is 2 gal/min.  We do not know which pool has 108 gallons of water in it.  If it's Pool A, then the time required to empty Pool A is

108 gallons  
------------------- = 54 minutes
2 gallons/min 

If it's Pool B, then we can represent the amount of water in Pool B by b.  Then the time required to empty Pool B is 

   b (gallons)
------------------ = (b/5) minutes
5 gallons/min
