Percent:

[tex]$60 \%$[/tex] means 60 for every 100 or 6 for every 10. 537 has 5 hundreds and about 4 tens [tex]$(37 \approx 40)$[/tex].

Try These Together: [tex]$(60 \times 5) + (6 \times 4) = 300 + 24$[/tex] or 324.

1. What fraction could you use to estimate [tex]$34 \%$[/tex] of a number?

D. 83

Answer :

Sure! Let's go through each part of the problem step by step to estimate the different percentages and values.

1. Estimate 34% of a number using a fraction:
- 34% is close to 33%, which is approximately one-third, or [tex]\( \frac{1}{3} \)[/tex].

2. Estimate a percent for 29 out of 40:
- 29 out of 40 is close to 30 out of 40. Simplifying 30 out of 40 gives us [tex]\( \frac{30}{40} = 0.75 \)[/tex]. So, the estimated percentage is 75%.

3. Write Fraction, Mixed Number, or Whole Number:

- 110%:
- 110% is 1 whole plus 10%, which can be expressed as 1.1 or [tex]\( 1 + 0.1 \)[/tex].

- 22%:
- 22% is close to 25%, which is [tex]\( \frac{1}{4} \)[/tex].

- 8.5%:
- 8.5% is close to 10%, which is [tex]\( \frac{1}{10} \)[/tex].

- 49%:
- 49% is close to 50%, which is [tex]\( \frac{1}{2} \)[/tex].

- 41%:
- 41% is close to 33%, which is approximately [tex]\( \frac{1}{3} \)[/tex].

4. Estimate:

- 430%:
- 430% means 4 wholes and an additional 30%, which we can estimate as 4.3.

- 13% of 79:
- Calculating 13% of 79 gives approximately 10.27.

- 58% of 190:
- Calculating 58% of 190 gives about 110.2.

- 109% of 500:
- Calculating 109% of 500 results in 545.

- 73% of 21:
- Calculating 73% of 21 gives about 15.33.

- 98% of 11:
- Calculating 98% of 11 results in approximately 10.78.

- 41% of 20:
- Calculating 41% of 20 gives us 8.2.

- 87% of 90:
- Calculating 87% of 90 results in approximately 78.3.

- 31% of 87:
- Calculating 31% of 87 gives about 26.97.

5. Estimate Each Percent:

- 19 out of 39:
- Calculating 19 out of 39 gives an estimated percentage of about 48.72%.

- 20 out of 55:
- Calculating 20 out of 55 results in approximately 36.36%.

- 4 out of 300:
- Calculating 4 out of 300 results in roughly 1.33%.

6. Nutrition Problem:
- If 30% of 205 calories come from fat, then the calories from fat would be about 61.5.

7. Multiple Choice Probability Question:
- Based on the provided context, the correct answer is 8.3, corresponding to choice C.
