Question

what rational number should be added -7/15 to get the sum as 2/3? need the steps

Answer 1

Let the rational number be x

• sum is given as 2/3

So,

x + ( -7 /15 ) = 2/3


$x + \frac{ - 7}{15} = \frac{2}{3}$


$x = \frac{2}{3} + \frac{7}{15}$


$x = \frac{10 + 7}{15}$


$x = \frac{17}{15}$
