Evaluate (frac{1}{2}+frac{3}{4}offrac{2}{5}div 1frac{3}{5})
-
A.
(frac{15}{16}) -
B.
(frac{11}{16}) -
C.
(frac{49}{50}) -
D.
(3frac{1}{5})
Correct Answer: Option B
Explanation
(frac{1}{2} + (frac{3}{4} text{ of } frac{2}{5}) div 1frac{3}{5})
= (frac{1}{2} + (frac{3}{4} times frac{2}{5}) div frac{8}{5})
= (frac{1}{2} + frac{3}{10} div frac{8}{5})
= (frac{1}{2} + (frac{3}{10} times frac{5}{8}))
= (frac{1}{2} + frac{3}{16})
= (frac{11}{16})
