Answer:
A= 27/8 feet
B= 21/4 feet
Step-by-step explanation:
<em>First, on both we need to convert to common denominators:</em>
<u><em>A.</em></u>
<u>Multiply:</u>
4 1/4 times 2= 4 2/8
<em>now we have to make 4 2/8 an improper fraction:</em>
4 times 8=32, 32+2=34
34/8
<u>Subtract the below ground length from the total length:</u>
34/8-7/8= <em><u>27/8</u></em>
<u>Repeat:</u>
<em><u>B.</u></em>
<u>Multiply:</u>
1 1/2 times 2= 1 2/4
<em>Now we have to make 1 2/4 and 6 3/4 improper fractions:</em>
1 times 4=4+2=6
6/4
6 times 4-24+3=27
27/4
<u>Subtract the below ground length from the total length:</u>
27/4-6/4= <em><u>21/4</u></em>
i hope this helps u pls give a brainliest and a thx ;)
