Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48

You distribute a 3/4 wherever you see a v
Use PEMDAS order of operations (parenthesis, exponents, multiply, divide, add, subtract)
12*3/4(32*9/16-8)
12*3/4(18-8)
12*3/4(10)
9*10
=90
Hope this helps
