Question

what should be subtracted from -2/3 to get -1

Answer 1

Answer:

We need to subtract $\frac{1}{3}$

Step-by-step explanation:

As we know that for subtracting $- \frac{2}{3}$ from a number to get $-1$ we will just simply subtract the later from the former given fraction which is $- \frac{2}{3}$

Therefore we have to do as follows:

Let the number that needs to be subtracted be n, therefore have:

$- \frac{2}{3} - x = -1$

⇒ $- x = - 1 + \frac{2}{3}$

⇒ $-x = \frac{-3 +2}{3}$

⇒ - x = - $\frac{1}{3}$

⇒ x = $\frac{1}{3}$

Hence $\frac{1}{3}$ needs to be subtracted so that we get -1 as the difference.

Answer 2

• We have to evaluate the above expression by using the given data.

             Given data:- $(-\frac{2}{3})-x= -1.$

             To find:- Value of the expression.

             Solution:-

• Let assume x to find the missing term.

• Then the result will be the solution for the given linear equation.

• By using the transposition method.

         we get,

        $-\frac{2}{3}-x=-1\\=>-\frac{2}{3}-x=-1 \\=>-x-\frac{2}{3}=-1\\=>-x=-1+\frac{2}{3}\\=>-x=-\frac{1}{3}\\=>x=\frac{1}{3}$

      Hence we will get $(-\frac{2}{3})-\frac{1}{3}= -1.$
