Question

1 1/4×-1 1/3 is equals to?​

Answer 1

Answer:
`-(5)/(12)`

Steps:

`1(1)/(4)* \left(-1\right)(1)/(3)`

Convert mixed numbers to improper fractions:
`1(1)/(4)`
`=(5)/(4)`

`=(5)/(4)* \left(-1\right)(1)/(3)`

`\mathrm{Apply\:the\:rule}:\quad \:a\left(-b\right)=-ab`

`(5)/(4)\left(-1\right)=-(5)/(4)* \:1`

`=-(5)/(4)* \:1* (1)/(3)`

`\mathrm{Apply\:rule}\:a* 1=a`

`=-(5)/(4)* (1)/(3)`

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

`(5)/(4)* (1)/(3)=(5* \:1)/(4* \:3)`

`=-(5* \:1)/(4* \:3)`

`\mathrm{Multiply\:the\:numbers:}\:5* \:1=5`

`=-(5)/(4* \:3)`

`\mathrm{Multiply\:the\:numbers:}\:4* \:3=12`

`=-(5)/(12)`
