Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "
Step-by-step explanation:
Modeling of Reality
Sometimes we have a real situation and we want to provide a mathematical model to explain it. But what if we have the model and need to imagine what the situation could be? It calls for our imagination and tries to figure out such a problem, given the answer
We can see a question mark multiplying the fraction 1/8 to produce a result of 3. This is a common proportion problem. This is my approach
"Peter makes $1/8 for every pencil he sells. Yesterday he made $3 by selling pencils, how many of them he sold? "
If we solved this question, we have to replace the ? for 24 and say Peter sold 24 pencils and made 24(1/8)=$3

The correct answer is 82% of 50 (41) / 170% of 30 (51) /65% of 80 (52)

Explanation:

The first step to know whether a value is greater than another is to find the value each percentage represents depending on the total. This process is shown below.

1. 65% of 80- This implies 80 is 100% and 85% needs to be found. Use the following formula:

80 / 100 = 0.8 x 65 = 52 or the total number divided by 100 and multiplied by the percentage you want to know

2. 82% of 50 - Repeat the same process

50 / 100 = 0.5 x 82 = 41

3. 170% of 30

30 / 100 = 0.3 x 170 = 51

4. Finally organize the values

82% of 50 (41)

170% of 30 (51)

65% of 80 (52)
