Question

2 1/5 divide by 4/-9

Answer 1

`(-99)/(20)`

Step-by-step explanation:

We want to find;

`2(1)/(5)\text{ divided by }(4)/(-9)`

Firstly, you change the mixed fraction to improper fraction and multiply with the reciprocal of the divisor;

`(11)/(5)*(-9)/(4)=(-99)/(20)`

we can now convert back to mixed fraction;

`-(99)/(20)=-4(19)/(20)`
