Answer:

To multiply two fractions, we multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. However, we are taught that when faced with a problem such as 3⁄5 ÷ 4⁄7, we should invert the second fraction and multiply.

The length of a rectangle is 2 m longer than its width. if the perimeter of the rectangle is 40 m , find its area.
vredina [299]
L=w+2 and 2w+2l=40

Substitute length for w+2 in perimeter formula.

2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9

l=w+2
l=9+2
l=11

a=lw=11*9=99 meters

Rachel buys 1 gallon of milk. Her sister Abby uses 1 1 2 quarts of the milk in a recipe. Then her mother uses 3 cups of the milk
mrs_skeptik [129]

1 Gallon is equal to 4 Quarts.

4-1\frac{1}{2} =2\frac{1}{2}

2\frac{1}{2} Quarts is equal to 10 Cups.

10-3=7

There are 7 Cups left.

7 Cups is equal to 56 Fluid Ounces.

Jill's mother limited her xbox 1 playing to 10 hours per week. she played on only four days, a different amount of time each day
Brrunno [24]
You have to find out how much time she played on Saturday, Wednesday, Friday, and Sunday. Let's look at the facts.
Sunday: No info is given.
Friday: She played the least of all four days
Saturday: Twice as much as Wednesday
Wednesday: No info is given.

We can write a problem and solve from this information. Let's use the variable W for Wednesday. Saturday is 2W. So whatever number Wednesday has, multiply it by 2. All of the total numbers should equal 10.

Since Friday was played the least amount, we know that every other day has to be at least 2 hours or above, so that Friday can be 1 hour. Sunday we have no info given.

This is a bit of guess and see for this problem. Let's say that Friday was 1 hour, Wednesday was 2, Sunday was 3, and Saturday was 4. Total that equals 10. Let's check to varify that these numbers are correct.

Friday was the least amount of hours of any day, which is why it is 1.
Wednesday had 2 hours, and Saturday had twice that many, which is 4.
Sunday has 3 hours.

In short, your answer would be: Friday 1 hour, Wednesday 2 hours, Sunday 3 hours, and Saturday 4 hours. I hope I explained it wel
