-20 • 3<br> ——————— =<br> -30 ÷ 3
luda_lava [24]

-20 * 3 / -30 / 3

First multiply the top and divide the bottom to simplify the problem:

-20 * 3 = -60


-30/3 = -10


Now you have -60 / -10


Divide:

-60 / -10 = 6

Chloe needs to swim a total of 9 miles this week. So far this week , she swam 5 5/8 miles. Use the equation 5 5/8 + m =9 to find
pshichka [43]

Alright, so all we have to do here is solve the equation!

5 5/8 + m = 9

m = 9 - 5 5/8

Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).

m = 8 8/8 - 5 5/8

Then we can subtract fairly easily!

m = (8 - 5) + (8/8 - 5/8)

m = 3 3/8 miles

Hope this helps!! :)
