To find the total change in the stock price, let's break down the given information step by step.
1. The stock gained 2 7/8 points.
To calculate this, add 2 to 7/8.
2 + 7/8 = 16/8 + 7/8 = 23/8.
2. The stock then lost 1 3/4 points.
To calculate this, subtract 1 from 3/4.
1 - 3/4 = 4/4 - 3/4 = 1/4.
3. The stock gained 1/2 point.
No calculation is needed for this step since it is a simple addition.
4. Finally, the stock lost 5 points.
No calculation is needed for this step since it is a simple subtraction.
Now, let's add up all the changes to find the total change in the stock price:
2 7/8 + (-1 3/4) + 1/2 + (-5).
To add mixed numbers, you need a common denominator. The lowest common denominator for 8, 4, and 1 is 8.
(23/8) + (-7/4) + (1/2) + (-40/8).
Converting all the fractions to have a denominator of 8:
(23/8) + (-14/8) + (4/8) + (-40/8) = -27/8.
Therefore, the total change in the stock price is -27/8.
To write this as a mixed number, divide 27 by 8: 27 ÷ 8 = 3 with a remainder of 3.
So, the total change in the stock price is -3 3/8.
Yes, your answer of -3 3/8 is correct!
