Question

what should you be substracted from the rational number 5/4 to get 1/2​

Answer 1

Step-by-step explanation:

5/4 -x =1/2

x=5/4-1/2

x=3/4

Answer 2

Appropriate Question -

• What should be subtracted from the rational number 5/4 to get 1/2?

Answer -

• The required number is 3/4.

To find -

• The number which should be subtracted from the rational number 5/4 to get 1/2.

Step-by-step explanation -

Let the required number be "x".

Then -

• "x" subtracted from 5/4 will be equal to 1/2.

Therefore,

$\implies \sf \dfrac{5}{4} - x = \dfrac{1}{2}$

$\implies\sf \dfrac{5}{4} = \dfrac{1}{2} + x$

$\implies\sf \dfrac{5}{4} - \dfrac{1}{2} = x$

$\implies\sf \dfrac{(5 \times 1) - (1 \times 2)}{4}= x$

$\implies\sf x = \dfrac{5 - 2}{4}$

$\implies\sf x = \dfrac{3}{4}$

Hence -

• 3/4 should be subtracted from 5/4 to get 1/2.

• To check our answer, let's subtract 3/4 from 5/4 and see whether we get 1/2 or not!

$\implies\tt \dfrac{5}{4} - \dfrac{3}{4}$

$\implies\tt\dfrac{5 - 3}{4}$

$\implies\tt \cancel{\dfrac{2}{4}}$

$\implies\tt \dfrac{1}{2}$

We get 1/2 on subtracting 3/4 from 5/4.

Hence verified!
