Question

Is the product of x and y rational or irrational?


When x = 0.75 and y = 0.82

Answer 1

rational

Explanation:

A rational number can be expressed in the form

`(a)/(b)` ← where a and b are integers

Given

0.75 × 0.82

=
`(75)/(100)` ×
`(82)/(100)`

=
`(3)/(4)` ×
`(41)/(50)`

=
`(3(41))/(4(50))`

=
`(123)/(200)` ← rational number

Answer 2

Rational number is part of a whole number therefore both of them are rational
