Question

X=3/5 y=1/3 z=2 4/5 work out the value of z+ x * y

Answer 1

z+x×y

`(3)/(5) + (1)/(3) * (4)/(5)`

`(3)/(5) + (4)/(15)`

now, LCM of 5 and 15 is 15.

`(3 * 3)/(5 * 3) + (4)/(15)`

`(9)/(15) + (4)/(15)`

both fractions have same denominator so common HCF is 15

`(9 + 4)/(15)`

`(13)/(15)`
