3. 1/15

explanation:
-3/5 and -2/3 need the same denominator so multiply them so that they equal the same. so multiply -3/5 by 3 and then -2/3 by 5. so that equals: -9/15 -(-10/15). The minis a negative cancels out and it becomes plus. so -9 plus 10 is 1 and 15 stays the same. so 1/15.

4. -5.2

explanation:
a negative (-2.5) subtracted by a technically smaller negative (-5.2) will equal a positive number

5.B

It takes 40 minutes for 8 people to paint 4 walls. How many minutes does it take 19people to paint 7 walls?
Slav-nsk [51]
Hey hey!


56 would be the answer.

WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.

Here’s how I got the answer:

7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.

If that helped let me know by hitting the thanks button or reply with any help you need.

Have a FABULOUS DAYYY!
