Question

Simplify: $4\frac{5}{2}-2\frac{3}{8}+3\frac{7}{8}$.

• A. $\frac{145}{24}$
• B. $\frac{24}{145}$
• C. $\frac{144}{25}$
• D. $8$

Answer 1

The correct option is D $8$

$4\frac{5}{2}$=$\frac{13}{2}$, $2\frac{3}{8}$=$\frac{19}{8}$, $3\frac{7}{8}$=$\frac{31}{8}$

$4\frac{5}{2}-2\frac{3}{8}+3\frac{7}{8}$.=$\frac{13}{2}-\frac{19}{8}+\frac{31}{8}$

=$\frac{52}{8}-\frac{19}{8}+\frac{31}{8}=\frac{64}{8}=8$
