Question
Find the product of:
`(-22)/11` and `(-21)/11`
Advertisements
Solution
Given, `(-22)/11` and `(-21)/11`
∴ Product of rational numbers = `"Product of numerators"/"Product of denominators"`
= `((-22) xx (-21))/(11 xx 11)`
= `462/121`
= `(462 ÷ 11)/(121 ÷ 11)` ...[Dividing numerator and denominator by 11]
= `42/11`
