-1 1/4 x 9
What is the answer to that

Answer 1

`-11(1)/(4)`

Explanation:

Convert the mixed numbers into improper fractions and solve by multiplying the numerators and then the denominators.


`-1(1)/(4) *9`
Convert the mixed number into an improper fraction:

`-1(1)/(4) =-(5)/(4)`

`-(5)/(4) *(9)/(1)`
Solve:

`-5*9=-45`

`-4*1=-4`

`=-(45)/(4)`
Convert the improper fraction back into a mixed number:

`-(45)/(4) =45/4=11(1)/(4)`

`=-11(1)/(4)`
