Tom has 7/8 cup of olive oil. He uses 1/2 cup to make salad dressing and 1/4 cup to make tomato sauce. How much olive oil does Tom have left?

Answers

Half of eight equals 4, so Tom will lose 4/8 to the salad dressing. one fourth of eight would be 2/8. So 2/8 + 4/8 = 6/8. Now 6/8 subtracted from 7/8 = your answer, 1/8!

Hope this helps! : )
Using our common denominators, we can convert 1/2 to 4/8, and 1/4 to 2/8. As 2+4 = 6, we can subtract our used olive oil (6/8) from our total (7/8), leaving us with 1/8 a cup olive oil.

A dog runs 9.5 mi in 0.5 h. The distance the dog travels varies directly with the amount of time it runs.How many miles will it run in 1.75 h?

mi

Answers

We divide 9.5 / 0.5 to see how much it runs in 1 hour.

9.5 / 0.5 = 19

So it runs 19 miles in 1 hour.

Now we multiply 1.75 to 19 miles.

1.75 * 19 = 33.25

So he will run 33.25 miles in 1.75 hours.
