Question

3/11 x 3/4 x 4 Please help I have no idea how to do this

Answer 1

`\bold{(9)/(11)}`

Explanation:

I will use the dot notation for multiplication

We have

`(3)/(11)\cdot (3)/(4)\cdot \:4`

Convert 4 to a fraction:

`4=(4)/(1)`

Therefore

`(3)/(11)\cdot (3)/(4)\cdot \:4 \\\\= (3)/(11)\cdot (3)/(4)\cdot \frac{\cancel {4}}{1}\\\\`

Cross-cancel common factor 4

`=(3)/(11)\cdot (3)/(1)`

`\mathrm{Apply\:the\:fraction\:rule}:\quad (a)/(b)\cdot (c)/(d)=(a\:\cdot \:c)/(b\:\cdot \:d)`

`=(3\cdot \:3)/(11\cdot \:1)`

`=\bold{(9)/(11)}`
