5. 7/64

Step-by-step explanation:

For I think all of these problems, I used KCF, you might know this already but, it's Keep, Change, Flip.

1. m ÷ n, place your values into the variables.

1/4 ÷  4/5   We keep 1/4 the same, change ÷ to multiplication and flip 4/5 to 5/4

1/4 * 5/4 = multiply across. 5/16 we can't simplify.

2.  2/9 ÷ 4/6 =  2/9 * 6/4 = 12/36 and simplify that to 1/3. 12 can go into 36 three times.

3. For this, we need to get the variable r by itself. And to do that we do reverse order of operations. 13r is multiplication, so we divide both sides by 13 to get r by itself.

13r = 3/7 would be r= 3/91

4. We have to turn each fraction into a mixed number.

6 1/4 would equal 25/4 because we times 4 by 6, 24, and add the one, 25.

3 1/20 would equal 61/20

25/4 ÷ 61/20 = 500/4 = 125/61 = 2 and 3/61

5. We can put 8 over 1, 8/1

7/8 ÷  8/1 then Keep, change, flip

7/8 * 1/8 multiply across

7/64

3+11

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
