My question is how do you get the answer 5/17?
When you multiply both the num and den straight accross you get 60/204. Simplify by dividing both numbers by 4 you have 15/51 divide both by 3 to further simplify and you get 5/17
This is correct ~ you cross cancel to reduce before you multiply, then reduce by a factor of two. Your final answer should be 5/17.
Quoting ballerina.2006:6 and the 12 reduce to 1 and 21/17 times 10/210 times 1= 1017 times 2 =34Reduce down and you get 5/17
