Tanya exercised for 30 minutes. She noted the calories burned three times during her workout. How can Tanya use this information to find how many calories she burned after 15 minutes of exercise?

Tanya can easily use this information to set up a proportion to find out how many calories she can burn in 15 minutes.

Let c = calories

30/15 = 3/c

15(3) = 30c

45 = 30c

45/30 = c

3/2 = c

Tanya burned 3/2 calories after 15 minutes of exercising.

I think math is a good way to keep memory alive and well.

Did you not notice that 30/15= 2?

2= 3/c is much simpler to solve.
