You can put this solution on YOUR website!
I would say that if you have a ratio of two numbers, it means to divide the two numbers!
2/3 : 5/8 really means 2/3 divided by 5/8.

This in turn means %282%2F3%29+%2A+%288%2F5%29, so you would multiply 2 times 8 and divide by 3 times 5. Answer here is 16%2F15. Is that what you meant by cross multiply??
