Question

What should be added to -7/8 to get 5/9

Answer 1

A number should be added to -7/8 to get 5/9
Let the number be x
x-7/8=5/9
x=5/9+7/8
x=[(5×8)+(7×9)]/(9×8)
x=(40+63)/72
x=103/72

Answer 2

Answer:

$\frac{103}{72} \:should\: be\:\\ added\: to\: \frac{-7}{8} \:to \:get\: \frac{5}{9}$

Step-by-step explanation:

$Let \:x\: should \:be \:added \:to\\\frac{-7}{8} \: to \: get \: \frac{5}{9}$

$x + \left(\frac{-7}{8}\right)=\frac{5}{9}$

$\implies x -\frac{7}{8}=\frac{5}{9}$

$\implies x = \frac{5}{9}+\frac{7}{8}$

$\implies x = \frac{5\times8+7\times9}{72}$

$\implies x = \frac{40+63}{72}$

=$\frac{103}{72}$

Therefore,

$\frac{103}{72} \:should\: be\:\\ added\: to\: \frac{-7}{8} \:to \:get\: \frac{5}{9}$
