Question

8.What should be subtracted from -2/5 to get 5/6?

Answer 1

Given: $-\frac{2}{5} -x=\frac{5}{6}$

We have to find the missing number.

• By using the concept of equation shifting, we are solving the above equation.  
• For this, we will separate the variables on one side and the constant on another side.
• Then, we will simplify the equation.

We are solving in the following way:

Let assume the missing number be$x$.

Now, from the given statement we can write:

$-\frac{2}{5} -x=\frac{5}{6}$

$=>-x=\frac{5}{6} +\frac{2}{5} \\\\=>-x=\frac{37}{30} \\\\=>x=-\frac{37}{30}$

Hence, the missing number will be$-\frac{37}{30}$.

Answer 2

Answer:

$- x = \frac{ - 2}{5} + \frac{5}{6} . \\ - x = \frac{ - 37}{30} . \\ x = \frac{37}{30} .$
