Question

Real numbersA stock lost 8 and 3/8 on Monday, 1 and 5/8 points on Tuesday. On Wednesday, it gained 13 points. What was the net gain or loss of the stocks for these three days?

Answer 1

Answer: The net gain was 3 stocks for these three days.

Step-by-step explanation

Given

• Monday: lost 8 and 3/8.

,

• Tuesday: lost 1 and 5/8 points.

,

• Wednesday: gained 13 points.

Procedure

To calculate the net gain, we have to add all the values we are giving, considering that the stock lost will have a negative sign:

`\text{Net gain}=Gains-losses`

0. Calculating the losses

We have to mixed numbers, for which we can add the whole numbers and the fractions separately.

• Whole numbers

`-8-1=-9`

• Fractions

`-(3)/(8)-(5)/(8)=-(8)/(8)=-1`

At last, we add both results and we get the losses:

`losses=-9-1=-10`

2. Calculating the gains

As we only have one quantity, there is no need for calculations:

`Gains=13`

3. Calculating net gain

Finally, we put both quantities in the formula:

`\text{Net gain}=13-10=3`
