To find the best estimate for 320.8, you can think of it in terms of rounding or simplifying the number by identifying values that might be close to it.
If you were to rough it out, you could consider dividing 320 by a number that approximates these answers.
When we divide:
- 320.8 by 16: \( 320.8 ÷ 16 = 20.4 \)
- 320.8 by 25.6: \( 320.8 ÷ 25.6 = 12.5 \)
- 320.8 by 22.4: \( 320.8 ÷ 22.4 = 14.3 \)
- 320.8 by 32: \( 320.8 ÷ 32 = 10.025 \)
None of the responses give a direct estimation, but if you are looking for the best estimation based on the value of 320.8 divided by different numbers, the closest one is probably 16, as it gives you the higher number of division closer to that range.
So, the best estimate for 320.8 in the provided options is 16.
