Ok so this all about subtracting fractions this is what you want to do:
you can change 8 3/4 and 4 2/3 to have the same value and deominator
8 3/4 = 8 9/12(multiply both sides by 3)
4 2/3 = 4 8/12(multiply both sides by 4)
you do this because 12 is divisible by 3 and 4
then, subtract 4 8/12 from 8 9/12 because John is using some of the wood his dad gave him.
then subtract once again, taking 11/2 away from your difference.
again match the deominator of 11/2 to the deominator of your difference which should be 12. another divisible of 12 is 2 and 6.
11/2 = 66/12 = 5 6/12(multiply both the top and bottom by 6)
and start subtracting.
so John should have -1 5/12(?) wood left

Answer:
162 in
Step-by-step explanation:
Split this shape into two rectangles:
The big rectangle has a base of 16 and a height of 7 (subtract 12-5=7 for height) Multiply base*height to get area of big rectangle:
16*7 = 112 in
The small rectangle has a base of 10 and a height of 5. Mulitply base*height to get area of small rectangle:
10*5 = 50 in
Add both areas together:
112+50= 162 inches
A) w + d = 799
B) w = d + 49
B) w -d = 49
Adding A & B
2w = 848
washer = 424
w -49 = d
dryer = 424 -49
dryer = 375
7.89 is greater than 7.189, 6.03 is equal to 6.030, because that last zero doesn't really change anything it cancels itself out
