So for example 4/2 is a improper fraction. First think how many times can two go into 4 and that is 2 so the answer is two. Let's try 7/4. 4 can go into 7 one time but there is some reminders so u take the remainder and use it as the numerator. Then u keep the same denominator and so the answer is 1 3/4

Answer:

By indicating, through the whole number of the mixed fraction, the lower boundary in which the fraction lies.

Step-by-step explanation:

Improper fractions can be expressed as mixed numbers by performing a división of numerator by denominator and expressing the remainder as fraction. Example 6/4 is equal to 1 2/4 or 1.5 that is the number of times 6 can be divided by 4 and the remainder of two expressed as a fraction. The whole number of the mixed number is the lower boundary whole number of 6/4. The upper boundary is this whole number + 1 , in this case 1+1 = 2 . So, by using the mixed fraction we can see that 6/4 is between 1 and 2.

Mario and Luigi were selling coupon books for the Video game club fundraiser. Apparently, Mario is a much better salesperson, be

sattari [20]

Answer: the total number of coupon books sold is 20.

Step-by-step explanation:

Let x represent the number of coupon books that Mario sold.

Let y represent the number of coupon books that Luigi sold.

Apparently, Mario is a much better salesperson, because he sold 4 times as many coupon books as Luigi. This is expressed as

x = 4y

If Luigi sold 12 fewer coupon books than Mario, the expression would be

x = y + 12 - - - - - - - - - - -- -1

Substituting x = 4y into equation 1, it becomes

4y = y + 12

4y - y = 12

3y = 12

y = 12/3

y = 4

x = 4y = 4 × 4

x = 16

The total number of coupon books that the two boys sold is

4 + 16 = 20

The formula A=12(b+c)h. Write the equation in term of c?

Lisa [10]

Answer:

$c = \frac{A}{12h} - b$

Step-by-step explanation:

Okay, so the goal is to isolate c on one side with all the other terms on the other side. So, let's start by dividing both sides with 12h. After we do that, we will be left with $\frac{A}{12h} = b+c$ . Now, we can subtract both sides by b, and we will be left with $\frac{A}{12h} - b = c$ . Yay! We've now isolated c and that is our final answer!

Hope this helped! :)

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run, How many runs can we paint?

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run. To find the amount of runs you can paint, you have to divide the total by the amount for each run.

$7 \div \frac{5}{9}$
