Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Divide both sides by 20:</u>
<u>Simplify:</u>
80 miles per hour is 128.74752 kilometers per hour
Keep the denominators the same and subtract the numerators. So for example in your example:
7/8 - 3/8
Leave the 8 alone. Subtract 3 from 7.
7 - 3 = 4
So answer is:
4/8
Sometimes they may have to simplify the answer, and in this case, 4/8 could be simplified to 1/2
