Hi @PrettyEyes

It looks like the fractions didn't copy over right - do you have a screenshot of the problem?

well your problem is missing a bunch of numbers...

PrettyEyes · Answer

She adds 3/10 of a fluid ounce of red to 11/15 of a fluid ounce of blue to make 1 1/30 fluid ounces of purple.

Angle · Answer

Those are some ugly numbers for a math problem... ugh
