How can you tell before you divide 387 by 4 that the first digit of the quotient is in the tens place?
3 is not evenly divisible by 4
6x 1 = 6
916 : 3 =305
Explain why estimating before u divide
I don't get it
To determine if the first digit of the quotient is in the tens place before performing the division, you need to consider the divisor and the dividend.
In this case, the dividend is 387, and the divisor is 4. To understand if the first digit of the quotient is in the tens place, we need to compare the number 4 to multiples of 10 until we find a multiple that is greater than or equal to 387.
Here's the step-by-step process to determine this:
1. Start with the divisor, which is 4, and compare it to multiples of 10:
- 4 x 1 = 4
- 4 x 10 = 40
- 4 x 100 = 400
2. Since 40 is less than 387, but 400 is greater, we know that the first digit of the quotient will be in the tens place.
Therefore, before dividing 387 by 4, you can determine that the first digit of the quotient will be in the tens place by comparing the divisor (4) to multiples of 10.
