Subtract: (- 16)/21 "From" 1

Subtract: `(- 16)/21 "from" 1`

Sum

`(- 16)/21 "from" 1`

`= 1/1 - ((- 16)/21)`

`= 1/1 + 16/21 = (1 xx 21 + 16)/21`

`= (21 + 16)/21 = 37/21`

Chapter 2 Rational Numbers
Exercise 2 (C) | Q 6.4

Fill in the blank:

`(-5)/8` and `3/10` are on the ________ side of zero

Add: `(-4)/9 "and" 2/9`

Multiply: `1 1/8 "and" 10 2/3`

Multiply: `(-13)/15 "and" (-25)/26`

Multiply: `1 1/6 "and" 18`

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

Divide: `35 "by" (- 7)/9`

By what rational number should we multiply `20/-9`, so that the product may be `(-5)/9`?

Evaluate: `7/-26 + 16/39`

The sum of two rational numbers is `(-3)/8`. If one of them is `3/16` find the other,
