Question

Can you show me how to reduce 99/143?

Answer 1

`99|3\\33|3\\11|11\\.\ 1|\\99=3*3*\fbox{11}\\\\143|11\\.\ 13|13\\.\ \ 1|\\143=\fbox{11}*13\\\\therefore:(99)/(143)=\frac{3*3*\fbox{11}}{13*\fbox{11}}=(3*3)/(13)=\boxed{\boxed{(9)/(13)}}`

Answer 2

To reduce a fraction fully, divide the denominator and numerator by their greatest common factor.

Factors of 99: 1, 3, 9, 11, 33, 99
Factors of 143: 1, 11, 13, 143
Common Factors: 1, 11
Great Common Factor: 11


`(99)/(11)=9 \\ \\ (143)/(11)=13 \\ \\ (99)/(143) = (9)/(13)`
