Following the order of operations, we first solve the problem in parentheses:

3+5x4÷936x4(7+80)x4÷7 = 3+5*4÷936*4*87*4÷7

As there are no exponents, we work on the multiplication/division, in order:

3+5*4÷936*4*87*4÷7 = 3+20÷936*4*87*4÷7

= 3+(5/234)*4*87*4÷7

= 3+(10/117)*87*4÷7

= 3+(870/117)*4÷7

= 3+(3480/117)÷7

= 3 + (3480/819)

= 5937/819

hello.

here is the step by step

follow pemdas, which means we do parenthesis first. (7+80) = 87

solve left to right, following * and / signs. 5 * 4 = 20

20 / 936 = ~0.02

0.02 * 4 = 0.08

0.08 * 4 = 0.32

0.32 / 7 = ~0.045

0.045 will be your final answer.

hope this helped
