Can you please help, this is the last day to complete my homework and I have been trying to figure this out

Answer:
5 31/136
Step-by-step explanation:
12+7/8-(1+1/7+3+1/2)(2-1+3/17) (sorry for the addition signs I can't write fractions)
add/subtract
12+7/8-(65/14)(14/17)
multiply
12+7/8-65/17
subtract
5 31/136
