Hi there,
I am in need of some clarification. When multiplying fractions, I know it is usually better (sometimes necessary) to reduce first. The following, for example, I understand:
360/121 x 77/900 = 2/121 x 77/5 = 2/11 x 7/5 = 14/55
360 and 900 are both divisible by 180, and 121 and 77 are both divisible by 11, so finding a solution makes sense to me. What happens when:
353/121 x 74/900
Is this a straight multiplication? 353 x 74 and 121 x 900? And from there, are there any rules for reducing?
Any help would be much appreciated.
