Question

What is the value of the expression below? 3 1 over 4 - 1 7 over 8

Answer 1

The value of the expression is;

$1\frac{3}{8}$

Here, we want to make a fraction subtraction

To do this, we will have to convert the mixed fraction to improper fraction and then proceed to subtract

To make the fraction improper, we multiply the denominator by the stand-alone number and add the numerator;

so we have;

$\begin{gathered} 3\frac{1}{4}\text{ = }\frac{13}{4} \\ 1\frac{7}{8}\text{ = }\frac{15}{8} \\ \\ \frac{13}{4}-\frac{15}{8}\text{ = }\frac{2(13)-15}{8}\text{ = }\frac{26-15}{8}\text{ = }\frac{11}{8}\text{ = 1}\frac{3}{8} \end{gathered}$
