You can put this solution on YOUR website! I changed your question to make it look like an equation (without the words). You need to follow the order of operations here. Parentheses come first, so you have to solve the bottom part of the equation, which is . Start with the part in the parentheses, which is 3*7+4. Multiplication comes before addition, so do 3x7, which is 21...then add 4...which is 25.
After that, you have the bottom part of the equation that looks like . Simply multiply 5x25, which is 125.
The final part is to put the top back on the problem, which looks like: 250/125. Divide this out, and your answer is 2.
