Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight training is 3 to 2. How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training
Setup the ratio given to you;
3%2F2
Now it says she spends 250 min/wk exercising, so we will make this the next ratio with 250 as denominator;
x%2F250
Now make each ratio equal to each other and cross multiply;
3%2F2+=+x%2F250
2x=750
x=375
