Chapter 2 Rational Numbers
Exercise 2 (C) | Q 6.3

Find three rational numbers equivalent to `8/-15`

Arrange the given rational numbers in descending order:

`3/-10, (-13)/30 "and" 8/-20`

Evaluate: `(-8)/9 + 4/9 + (-2)/9`

Evaluate: `(-45)/39 xx (-13)/15`

Multiply: ` 35 "and" (-18)/25`

Evaluate: `((-5)/9 xx 6/-25) + (24/21 xx 7/8)`

Evaluate: `((-4)/5 xx 3/2) + (9/-5 xx 10/3) - ((-3)/2 xx (-1)/4)`

Divide: `16/-5 "by" (-8)/7`

The product of two numbers is 14. If one of the numbers is `(-8)/7`, find the other.

Evaluate: `(-2)/3 + 3/4`
