13/3 + 5(5/4 - 3/2) ÷ 11/8=3 14/33133+5(5432)÷118=31433

Explanation:

We use PEMDAS as order of operations i.e. first parentheses. then exponents (none here), then multiplication and division and finally addition and subtraction.

Hence 13/3 + 5(5/4 - 3/2) ÷ 11/8133+5(5432)÷118

= 13/3 + 5(5/4 - 6/4) ÷ 11/8133+5(5464)÷118

= 13/3 + 5( - 1/4) ÷ 11/8133+5(14)÷118 (solving parentheses)

= 13/3 - 5/4 xx 8/1113354×811 (multiplication and division)

= 13/3 - 5/cancel4^1 xx cancel8^2/11

= 13/3-10/11 (addition and subtraction)

= (13xx11)/(3xx11)-(10xx3)/(11xx3)

= 143/33-30/33

= 113/33

= 3 14/33
