Add `frac(7)(-11)` and `frac(3)(7).`

EXAMPLE 6. Add frac(9)(-16) and frac(-5)(-12).

EXAMPLE 1. Add frac(5)(9) and frac(-13)(9).

. Add frac(-2)(3) and frac(3)(4).

EXAMPLE 5. Add frac(-3)(8) and frac(-5)(12).

HCF of frac(2)(3) , frac(4)(5) and frac(6)(7) is

frac(5)(2), frac(7)(3) and frac(5)(2) xx frac(7)(3) . Let's calculate which one of the these is greatest.

Arrange the fractions frac(5)(6) , frac(3)(4) , frac(4)(13) and frac(7)(9) in ascending order.

What is the correct ascending order for the given fractions? (A) frac(22)(7) , frac(13)(17) , frac(11)(19) , frac(2)(3) , (B) frac(11)(19) , frac(2)(3) , frac(13)(17) , frac(22)(7) , (C ) frac(2)(3) , frac(11)(19) , frac(13)(17) , frac(22)(7) (D) frac(2)(3) , frac(13)(17) , frac(11)(19) , frac(22)(7) .

A rational number is such that when you multiply it by frac(5)(2) and frac(2)(3) add to the product, you get -frac(7)(12) . What is the number?

Simplfy frac(2frac(3)(4) (frac(5)(6) div frac(7)(8) xx (frac(1)(3)+ (1)/(4) + frac(5) (7) div frac(3)(4) of frac(3)(7)))
