First, you find the rate at which Jeffery types.
110 divides by 2.75. This makes 40.
Then to find the amount of words he types in 4.25 minutes,
40 x 4.25. This makes 170.
So Jeffery can type 170 words in 4 1/4 minutes.

To find this answer, we should subtract 2 1/2 from 3 1/4. The simplest way to do this is to turn them into improper fractions, found the least common denominator, and subtract the numerators.
3 1/4=13/4
2 1/2=5/2
The least common multiple is 4, so we should multiply the numerator and denominator of 5/2 by 2.
5/2=10/4
Now we can just subtract the numerators.
13/4-10/4=3/4
Using the math above, we can see that it saves D. 3/4 hours.
