Find X, Such That: 3/7 = "X"/-35

Find x, such that: `3/7 = "x"/-35`

Sum

`7/-4 = "x"/8`

`=> (3 xx -5)/(7 xx - 5) = "x"/-35`

`=> (-15)/-35 = "x"/-35`

⇒ x = - 15

Exercise 2 (A) | Q 12.3

Find three rational numbers equivalent to `4/-7`

Express the following rational number to the lowest term: `12/15`

Express the following rational number in the standard form. `4/-9`

Arrange the given rational numbers in ascending order:

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

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

Evaluate: `((-8)/9) xx ((-3)/16)`

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

Evaluate: `(-6 xx 5/18) - (- 4 2/9)`

Evaluate: `-1 + 2/-3 + 5/6`

Evaluate:

`((-13)/7 xx (- 35)/39) - ((-7)/45 xx (9)/14)`
