Answer:
128
Step-by-step explanation:
Set this up as a proportion with miles on the top and km on the bottom:

If we want to know how many km are in 80 miles, we put the variable with the km stuff on the bottom and 80 on top and cross multiply to solve for the variable:
so
5x = 640 and
x = 128
That means that 80 miles is equivalent to 128 km
X= 5 and it also equals -5
Steps:
1. Do a proportion
X/220=60/100
2. Do 60 times 220 which equals 13,200
3. Do 13,200 divided by 100 which equals 132
4. 132 is how many are carbohydrates
5. Do 220 - 132= 88
6. Your answer is 88
