Question

Fraction multiplication both mixed fraction -always cross reduce 1 2/3 * 1 7/10

Answer 1

`1(2)/(3) * 1 (7)/(10)`

Change to improper fractions:

`= (5)/(3) * (17)/(10)`

Cancel common factor 5:

`= (1 * 5)/(3) * (17)/(2 * 5)`


`= \frac{1} {3} * (17)/(2)`

Combine:

`= \frac{17} {6}`

Simplify:

`= 2\frac{5} {6}`

Answer 2

There are 2 mixed numbers in 1 2/3 * 1 7/10. One is 1 2/3; the other is 1 7/10.

Convert both to improper fractions: 1 2/3 becomes 5/2, and 1 7/10 becomes 17/10.
5 17
Then your task is to multiply ---- * ----- , which, after reducing 5/10, becomes
2 10
