Question

What should be subtracted from -3/8 to get 4/7​

Answer 1

Here, we have to find a number that should be  subtracted from -3/8 to get 4/7​

Let us assume 'x' be the number that  subtracted from -3/8 to get 4/7​

It can be mathematically written as

$\frac{-3}{8} - x=\frac{4}{7}$

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

$x=\frac{-3}{8} -\frac{4}{7}$

$x=\frac{-21-32}{56}$

$x=\frac{-53}{56}$

So, -53/56  should be subtracted from -3/8 to get 4/7​

Answer 2

Given:

What should be subtracted from -3/8 to get 4/7

Let x be number that should be subtracted from -3/8 to get 4/7​

According to the question we have to write it as:

$\frac{-3}{8}-x=\frac{4}{7}$

$x=\frac{-53}{56}$$x=\frac{-3}{8} -\frac{4}{7}$

$x=\frac{-3\times7-4\times8}{8\times7}$

$x=\frac{-21-32}{56}$

$x=\frac{-53}{56}$

Hence -53/56 should be subtracted from -3/8 to get 4/7​
