Short Answer

Expert verified

The value of the given expression is $3 \frac{1}{20}$ .

Step by step solution

Step 1. Given information.

The given expression is:

$7 \frac{3}{4} - 4 \frac{7}{10}$

Step 2. Write the concept.

To add or subtract the fraction, the denominator must be the same.

Step 3. Write a mixed fraction to fraction form.

The given expression can be written as in below:

$7 \frac{3}{4} - 4 \frac{7}{10} = \frac{31}{4} - \frac{47}{10}$

Step 4. Solve the expression.

The expression $\frac{31}{4} - \frac{47}{10}$ can be solved below:

$\begin{array}{l} \frac{31}{4} - \frac{47}{10} = \frac{31 \times 5}{4 \times 5} - \frac{47 \times 2}{10 \times 2} \\ = \frac{155}{20} - \frac{94}{20} \\ = \frac{155 - 94}{20} \\ = \frac{61}{20} \end{array}$

Therefore,

$\begin{array}{l} 7 \frac{3}{4} - 4 \frac{7}{10} = \frac{61}{20} \\ = 3 \frac{1}{20} \end{array}$
