Idon't understand numbers 4-6. show work, you. c:

Question 4- You need to subtract the shortest bolt from the longest bolt, or 1 1/4 minus 3/8. Make 1 1/4 improper and make the denominator 8 so multiply 5x2=10 and 4x2=8. 10/8 - 3/8 equals 7/8 and thats your final answer. Hope this helped ;)

4. You subtract 1 1/4 to 3/8 but it’s the longest and shortest.
5 for this question you would add all the fractions together because it’s asking how long would it be if it was all put together.
6. You would multiply 9 and 7/8 because you have 9 bolts that all have the length of 7/8 and you want to know how long it would be.

Iwould say always for the both of them
