Question

Simplify: $3\frac{1}{2}+2\frac{5}{7}\times \frac{7}{19}-\frac{1}{2}÷2$

• A. $4\frac{1}{4}$
• B. $4\frac{1}{2}$
• C. $4\frac{3}{4}$
• D. None of the above

Answer 1

The correct option is A $4\frac{1}{4}$

By BODMAS rule,
$3\frac{1}{2}+2\frac{5}{7}\times 719-\frac{1}{2}÷2$
$=\frac{7}{2}+\frac{19}{7}\times \frac{7}{19}-\frac{1}{4}$
$=\frac{7}{2}+1-\frac{1}{4}=\frac{9}{2}-\frac{1}{4}=\frac{17}{4}=4\frac{1}{4}$
