10*9\1
WHAT WILL THE ANSWER BE AND HOW CAN I SOLVE IT ?

I do not know what the symbol is in front of the last digits. Please repost with clearer data. Thanks for asking.
10 times 9 divided by 1hkj
Hello! To calculate the upper and lower bounds of a calculation, you need to consider the range of possible values when rounding numbers to the nearest whole number.
For the first calculation, 400 divided by 60, we need to find the upper and lower bounds. To do this, we will first perform the calculation, and then round the result to the nearest whole number.
400 ÷ 60 = 6.666666...
Rounding this result to the nearest whole number, we get:
Upper bound: 7 (rounding up)
Lower bound: 6 (rounding down)
So the upper bound of 400 ÷ 60 is 7, and the lower bound is 6.
For the second calculation, 10 multiplied by 9, we perform the calculation and then round the result as well.
10 × 9 = 90
Rounding this result to the nearest whole number, we get:
Upper bound: 90
Lower bound: 90
Since 90 is already a whole number, the upper and lower bounds are both 90.
Therefore, the upper bound for 10 × 9 ÷ 1 is 90, and the lower bound is also 90.
To summarize:
- Upper bound of 400 ÷ 60 = 7
- Lower bound of 400 ÷ 60 = 6
- Upper bound of 10 × 9 ÷ 1 = 90
- Lower bound of 10 × 9 ÷ 1 = 90
