•PLEASE HELP

A= 27/8 feet

B= 21/4 feet

Step-by-step explanation:

First, on both we need to convert to common denominators:

A.

Multiply:

4 1/4 times 2= 4 2/8

now we have to make 4 2/8 an improper fraction:

4 times 8=32, 32+2=34

34/8

Subtract the below ground length from the total length:

34/8-7/8= 27/8

Repeat:

B.

Multiply:

1 1/2 times 2= 1 2/4

Now we have to make 1 2/4 and 6 3/4 improper fractions:

1 times 4=4+2=6

6/4

6 times 4-24+3=27

27/4

Subtract the below ground length from the total length:

27/4-6/4= 21/4

i hope this helps u pls give a brainliest and a thx ;)

the 4th choice is the correct one

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
