Simplify the following expression:

712\frac{7}{12} ÷ 110\frac{1}{10} of 23\frac{2}{3} - 53\frac{5}{3} x 910\frac{9}{10} + 58\frac{5}{8} ÷ 34\frac{3}{4} of 23\frac{2}{3}

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e.  8 12\frac{1}{2} 

 712\frac{7}{12} ÷ 110\frac{1}{10} of 23\frac{2}{3} - 53\frac{5}{3} x 910\frac{9}{10} + 58\frac{5}{8} ÷ 34\frac{3}{4} of 23\frac{2}{3}

Use BODMAS rule on the question :

=  712\frac{7}{12} ÷ 115\frac{1}{15} - 53\frac{5}{3} x 910\frac{9}{10} + 58\frac{5}{8} ÷ 12\frac{1}{2}

= 354\frac{35}{4} - 32\frac{3}{2} + 54\frac{5}{4}

= 35−6+54\frac{35-6+5}{4}

= 34/4 

= 8 12\frac{1}{2}
