Ineed to know the answer and steps to figure out, mark wants to paint a mural. he has 1 1/3 gallons of yellow paint, 1 1/4 gallons of green paint and 7/8 gallon of blue paint. mark plans to use 3/4 gallons of each paint color. how many gallons of paint will he have left after painting the mural?

Well, Mark has

1 1/3 of yellow paint

1 1/4 of green paint  and

7/8 of blue paint

now, bear in mind, the yellow is a bucket and 1/3 more, the green one is one bucket and 1/4 more and the blue is 7/8 which is almost 8/8, so is almost a bucketfull.

Then he's going to use 3/4 of each, so, we'd have to subtract 3/4 from each, and there'll be some left still in the paint bucket.

How many will he have left altogether?  well, we simply add the leftovers.

The answer to your question is d 68%
