Question

$what should be added to twice the ratinoal number \frac{ - 7}{3} \: to \: get \frac{3}{4 \}$

Answer 1

Let the number be 'a'

'a' should be added to twice the rational number -7/3 to get 3/4.

2(-7/3) + a = 3/4

-14/3 + a = 3/4

a = 3/4 + 14/3

a = (9+56)/12

a = 65/12

65/12 should be added to twice the rational number -7/3 to get 3/4

Answer 2

Heya !!!


Let X should be added to twice the Rational Number -7/3 to get 3/4




Therefore,



2 × -7/3 + X = 3/4



-14/3 + X = 3/4




-14 + 3X/3 = 3/4




4 ( -14X + 3X) = 9




-56 + 12X = 9




12X = 9 +56



12X = 65



X = 65/12






Hence,


65/12 should be added to twice of -7/3 to get 3/4.
