Question

subtract 7/2 and 7/4​

Answer 1

• As per the data given in the question, we have to find the value of the expression.

          Given data:-$\frac{7}{2} -\frac{7}{4}.$

         To find- Value of the given expression.

         Solution:-

• We will take the LCM of the denominators, and make denominators the same.

• We will Convert the given fractions to equivalent fractions with the denominator as the LCM.

• Adding the numerators over the denominators.

            $\frac{7}{2} -\frac{7}{4} \\=\frac{(4\times7)-(7\times2)}{4\times2} \\=\frac{28-14}{8}\\=\frac{14}{8} \\=\frac{7}{4} .$

      Hence we will get the value $\frac{7}{4} .$

Answer 2

Given values are,

$\frac{7}{2} , \frac{7}{4}$

Now we have to subtract these values.

$\frac{7}{2} - \frac{7}{4}$

In order to subtract the fractions, their denominators must be equal.

For this first we have find out the LCM of $2,4$

The LCM of $2,4$ is $4$

$\frac{7}{2}\times \frac{2}{2} - \frac{7}{4}$

$\frac{14}{4} -\frac{7}{4}$

$\frac{14-7}{4}$

$\frac{7}{4}$

Therefore, the final answer is $\frac{7}{4}$
