Question

a stock lost 7 1/8 points on monday and then another 1 7/8 points on tuesday. on wednesday, it gained 13 points. what was the net gain or loss of the stock for these three days? a gain of 4 points a loss of 22 points a gain of 7 3/4 points a gain of 18 1/4 points

Explanation:

Step1: Convert mixed - numbers to improper fractions

Loss on Monday: $7\frac{1}{8}=\frac{7\times8 + 1}{8}=\frac{57}{8}$; Loss on Tuesday: $1\frac{7}{8}=\frac{1\times8+7}{8}=\frac{15}{8}$; Gain on Wednesday: 13.

Step2: Calculate the total loss

Total loss in the first two days is $\frac{57}{8}+\frac{15}{8}=\frac{57 + 15}{8}=\frac{72}{8}=9$.

Step3: Calculate the net gain or loss

Net change = Gain on Wednesday - Total loss in first two days. So, $13-9 = 4$.

Answer:

a gain of 4 points
