Answer:
7/12
Step-by-step explanation:
You can pretend the given ratio units are the actual weights. Then the desired ratio is ...
book : mug = 7 : 5
book : (book +mug) = 7 : (7 +5) = 7 : 12
The weight of the book is 7/12 of the total weight.
12/80
=15 percent
There are 80 apples in the crate
Do 12 divided by 15 then multiply by 100 = 80
Remember to follow PEMDAS and the "left-to-right" rule
39 x 2 = 78
67 - 78 = -11
-11 + 26 + 78
Combine
(-11 + 26) + 78
15 + 78
93 is your answer
