Question

What should be added to -5/4 to get -1

Answer 1

Let x be added to -5/4 to get -1

So,

x + (-5/4) = -1

x = -1 + 5/4

x = -4 + 5/4

x = 1/4

So, 1/4 must be added to get -1.

Answer 2

To find:

what should be added to $-\frac{5}{4}$ to get -1

Solution:

Let x be the unknown number.

$-\frac{5}{4}+x=-1$

$x=-1 +\frac{5}{4}$

To make the denominator same multiply and divide first term by 4.

$x=-\frac{4}{4} +\frac{5}{4}$

$x=\frac{-4+5}{4}$

$x=\frac{1}{4}$

Therefore $\frac{1}{4}$ must be added to $-\frac{5}{4}$ to get -1.
