You mow 1/3 of the lawn. Your sister mows 2/5 of the lawn. What fraction of the lawn is left to mow?​

11/15

Step-by-step explanation:

YOu're gonna have to add the fractions together but since the denominators are different, you're gonna have to mutiply to find a common denominator. 15 is a common denominator between 3 and 5 so that's what I'll be using.

1/3 x 5/5 = 5/15    2/5 x 3/3 = 6/15

Since they now have common denominators, you can add them.

5/15 + 6/15 = 11/15

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
