The yoga class meets twice a week.

On Tuesdays, the ratio of men to women is 1:6.

On Thursdays, the ratio of men to women is 2:11.

On which day the ratio of women higher at the yoga class?

We can write ratios in fraction form

1:6 = 1/6

2:11 = 2/11

Therefore we can expand the fractions so that the bottom number will be the same

1/6 = 11/66

2/11 = 12/66

11 is less than 12, which means there's less men on tuesday.

Therfore on tuesday there should be more women.
