Question

The value of ( 3 /4 ) −3 is _____.​

Answer 1

Answer:

-9/4

Step-by-step explanation:

Answer 2

Given expression:

$(\frac {3} {4})-3$.

Number '$3$' can be written as $\frac {3} {1}$.

So, given expression becomes  $\frac {3} {4}- \frac {3} {1}$.

Here, denominators are different. So, we cannot add numerators.

The L.C.M. of $4$ and $1$ is $4$.

$=\frac {3} {4}-\frac {3\times4} {1\times4}$

$=\frac {3} {4}-\frac {12} {4}$

Now, denominators are same. So we can add numerators.

$=\frac {3-12} {4}$

$=\frac {-9} {4}$.

Therefore, the value of the given expression is $\frac {-9} {4}$.
