To estimate 93.7 ÷ 4.89, we should round both numbers to make the division simpler.
- Rounding 93.7 gives us approximately 94.
- Rounding 4.89 gives us approximately 5.
Now, we can estimate the division:
94 ÷ 5
However, looking at the options provided, the best fit for our estimation method is:
90 ÷ 5
This would also give an estimate close to the actual division.
