Question

• A. 1
• B. -1
• C. 2
• D. -2

Answer 1

Answer:

A. 1

Read Explanation:

$\frac{3\frac{1}{2}-2\frac{1}{3}-\frac{1}{3}}{(5\frac{1}{2}\times \frac{5}{11})-2 \frac{1}{3}} = \frac{\frac{7}{2}-\frac{7}{3}-\frac{1}{3}}{(\frac{11}{2}\times \frac{5}{11})-\frac{5}{3}}$

$=\frac{\frac{21-14-2}{6}}{\frac{5}{2}-\frac{5}{3}}$

$=\frac{\frac{5}{6}}{\frac{15-10}{6}}$

$= \frac{\frac{5}{6}}{\frac{5}{6}}$

$=1$
