Question

zoe has a goal to sell 100 t - shirts. use the double number line to find 50% of zoes goal.

Explanation:

Step1: Understand the goal

Zoe's goal is to sell 100 t - shirts. We need to find 50% of this goal.

Step2: Recall the percentage formula

To find a percentage of a number, we use the formula: $ \text{Percentage of number} = \frac{\text{Percentage}}{100}\times\text{Number} $
Here, the percentage is 50% and the number is 100. So we calculate $ \frac{50}{100}\times100 $

Step3: Simplify the calculation

$ \frac{50}{100}\times100 = 50 $
We can also use the double - number line. The number line for t - shirts goes from 0 to 100, and the percentage line goes from 0% to 100%. 50% is the mid - point of 0% and 100%, so the corresponding number of t - shirts should be the mid - point of 0 and 100, which is 50.

Answer:

50
