answer:
To estimate 66% of 34, you can use two different methods: rounding and proportional reasoning.
1. Rounding method:
- Round 66% to the nearest whole number, which is 70%.
- Calculate 70% of 34 by multiplying 34 by 0.70.
- 70% of 34 ≈ 0.70 * 34 ≈ 23.8 (rounded to the nearest tenth).
2. Proportional reasoning method:
- Recognize that 66% is approximately two-thirds (2/3) or 2 out of 3 parts.
- Divide 34 into three equal parts: 34 ÷ 3 ≈ 11.33 (rounded to the nearest hundredth).
- Multiply the result by 2 to find two-thirds of 34: 2 * 11.33 ≈ 22.67 (rounded to the nearest hundredth).
In conclusion, the most accurate way to estimate 66% of 34 would be using proportional reasoning, which gives an estimate of approximately 22.67. However, if you prefer a simpler approximation, rounding to the nearest tenth gives an estimate of approximately 23.8.
