(3 x (1/4) - (4/5) of (5/6))/(4 x (1/3) ÷ (1/5) - ((3/10) + 21 x (1/5))) - ((1 x (2/3)) of (1 x (1/2)) is equal to

Question

\(\frac{3\frac14-\frac45\,\text{of}\frac56}{4\frac13 ÷ \frac15-\big(\frac3{10}+21\frac15\big)}-\big(1\frac23\,\text{of}\,1\frac12\big)\) is equal to

(a) 9 

(b) 11\(\frac12\)

(c) 13 

(d) 15\(\frac12\)

Answer 1

(c) 13

\(\frac{3\frac14-\frac45\,\text{of}\frac56}{4\frac13 ÷ \frac15-\big(\frac3{10}+21\frac15\big)}-\big(1\frac23\,\text{of}\,1\frac12\big)\)

= \(\frac{31}{2} -\frac52=\frac{26}{2}=13.\)
