Question
Find the product:
`3/10 xx (-9)`
Solution
Given, `3/10 xx (- 9)`
= `3/10 xx (- 9)/1`
To get the product of two rational numbers, their numerator is multiplied by numerator and denominator by denominator.
= `(3 xx (- 9))/(10 xx 1)`
= `(- 27)/10`
Since, the numerator and denominator of the obtained rational number have no other factors except 1.
Hence, `(- 27)/10`
