Answer:
3(10)-7
Step-by-step explanation:
3(10)-7
Given:
The perimeter of a rectangular building is 1200 feet.
The width of the building is 2 feet less than three times the length.
To find:
Width of the building.
Solution:
Let length of the building be x.
Then, width = 3x-2
We know that,
Add 4 on both sides
Divide both sides by 8.
Now,
Therefore, the width of the building is 449.5 feet.

So when you divide fractions, you keep the first fraction (in this case 5/8) then change the sign from divide to multiply, then flip the second fraction (we’ll use 1/16 first)
So 5/8 times 16/1. 80/8. Simply to 10.
Now do the same with 5/8 and 1/32
5/8 times 32/1. 160/8. Simplify to 20.
So I good prediction would be 1/32 since you have to flip the divisor and multiply.
