Question

(7th grade math) Only adding/subtracting fractions, not too difficult :3



The price of a stock increased 1/2 cent Monday morning. On Monday afternoon, the price of the stock decreased 5/6 cent. On Tuesday morning, the price increased 1/4 cent. What is the overall change in the stock’s price?

−7/12 cent
−1/12 cent
1/12 cent
17/12 cents


I got 1/12, is that correct? And also, do I have to lay out the fraction as it says? For example:


The price of a stock increased 1/2 cent Monday morning. On Monday afternoon, the price of the stock decreased 5/6 cent
