Question

What number should be subracted from -4/5 to get -11/14?

Answer 1

Answer:

Given - No. subtracted from 0 to get -5/11

to fine- value of no.

solution -

Let the no. be X

0 - X= -5/11

-X= (-5/11)-0

-X= (-5/11)

X= 5/11

• What number should be subracted from -4/5 to get -11/14?

$\huge\mathfrak\pink{ \: \: \: \: Solution:}$

• Let the required number be x, then

$\sf{ \dfrac{-4}{5} ~ - x ~ = \dfrac{-11}{14} \implies \dfrac{-4}{5} = \dfrac{-11}{14} ~ + ~ x}$

$\implies\sf{ x = \dfrac{-4}{5} - (\dfrac{-11}{14}) = \dfrac{-4}{5} + \dfrac{11}{14}}$

$\large\tt\red{Note: LCM~ of~ 5~ and~ 14~ is~ 70.}$

$\implies\sf{ x = \dfrac{14 \times (-4) + 11 \times 5}{70}}$

$\huge\sf{ \frac{-56+55}{70} = }$$\huge\red{\sf{ \frac{-1}{70}}}$
