Question

What should be subtracted from −2/3 to get –1 ?

Answer 1

Here, we have to find a number that should be  subtracted from −2/3 to get –1

• Let us assume 'x' be the number that  subtracted from −2/3 to get –1

       It can be mathematically written as

      $\frac{-2}{3} -x=-1$

• Now in order to find the value of 'x' we will have to rearrange the equation

      $x=\frac{-2}{3} +1$

      $x=\frac{-2+3}{3}$

      $x=\frac{1}{3}$

So, 1/3  should be subtracted from −2/3 to get –1.

Answer 2

Answer:

according to question we have to find number to be subtracted from −2/3 to get –1  

Let the number which is to be subtracted be x

According to the question,

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

 $x = \frac{-2}{3} + 1$     -------------------------------------(By transposing terms)  

cross multiplying terms

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

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

Thus, 1/3  should be subtracted from -2/3 to get -1.
