$\frac{61}{2} \times ( \frac{8}{9} \div \frac{13}{18} ) + ( \frac{3}{4} ) {}^{2} \\ 30.5 \times ( \frac{8}{9} \times \frac{18}{13} ) + \frac{9}{16} \\ 30.5 \times \frac{16}{13} + \frac{9}{16} \\ \frac{61}{2} \times \frac{16}{13} + \frac{9}{16}$

=375.94

Answer 2

Use BODMAS
We get;
= 61/2 * 16/13 + 9/16 * 31/5
= 976/26 + 279/80
= 488/13 + 279/80
= [488*1040 + 279*1040]/1040
= 797680/1040
Answer = 767
