What is 1.5 divided by 1/6?
1 answer:
let's firstly convert the decimal 1.5 to a fraction, hmmm so it has one decimal, so we'll use a "1" with one zero on the denominator and lose the dot.

Perimeter = 2 1/8 + 3 1/2 + 2 1/2 = 7 (1 + 4 + 4)/8 = 7 9/8 = 8 1/8
I think $8. That’s the difference between the highest and lowest number.
The least common denominator is 36
Just plug the inequality in desmos and you get 7<x<13
