Exercise 2 (D) | Q 2.04

Arrange the given rational numbers in ascending order:

`7/10 , (-11)/-30 "and" 5/-15`

Add: `(-7)/26 "and" 7/-26`

Evaluate: `(- 9)/4 + 13/3 + 25/6`

Subtract: `(-4)/11 "from" -2`

Subtract: `5/8 "from" (-5)/16`

Evaluate: `2 14/25 xx ((-5)/16)`

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

A bus is moving with a speed of 65 `1/2` km per hour. How much distance will it cover in 1 `1/3` hours.

Divide: `21/44 "by" - 11/9`
