To choose the best number to subtract in the division problem 956 ÷ 87 using powers of 10, we should look for an approximate number that is close to 956 but manageable for division by 87.
Let's analyze the options:
1. **8,700**: This is far too large compared to 956, so it wouldn’t be a good choice.
2. **870**: This number is reasonably close to 956 and can be divided by 87 fairly easily. In fact, 87 is a little less than 870, so this could work.
3. **800**: While 800 is a reasonable close estimate, it might not utilize the full value of 956 for the first subtraction.
4. **87**: Subtracting 87 would not use much of the value of 956 and is less efficient for this division problem.
Given these options, the best choice for the first number to subtract in the division of 956 by 87 would be **870**.
