Question

What number should be subtracted from 3/7 to get 5/7 *
O - 217
2/7
hi
3/5
O 1/7​

Answer 1

Answer:

Let’s say that “x” should be subtracted from -5/3 to get -2/7. Then, we can write:

−5/3−x=−2/7

We can now add 5/3 to both sides of the equation. Then -x will be alone on one side:

−x=−2/7+5/3

Getting a common denominator for the terms on the right side results in:

−x=−6/21+35/21

Now, let’s add the two terms on the right side:

−x=29/21

So, now we know what -x is. To find x, we can both sides of the above equation by -1.

x=−29/21

Thus, 29/21 should be subtracted from 5/3 to get 2/7.

Answer 2

Answer:

$let \: the \: number = x$

$\frac{3}{7} - x = \frac{5}{7}$

$x = \frac{3}{7} - \frac{5}{7}$

$x = - \frac{2}{7}$
