Answer:

1. The difference between the hours when Steve runs than walk.

2. first, division and addition. then subtraction.

3.) 1/8

Step-by-step explanation:

2.) we need to find the greatest common denominator first so we need to divide and add. then lastly subtract.

3.) let h be the difference between the hour Steve runs and walks.

h = 7/8 - 3/4 — (they don't have the same denominator

so we need to find the GCF which we found that it is 8) divide 8 with the denominator then multiply the answer with the numerator) remember to take 8 as the numerator

7/8 stays as it is, while 3/4 becomes 6/8; let's go back to the formula

h = 7/8 – 6/8

= 1/8

ps. sorry medyo magulo
