Round 9.86-5.47 to the nearest whole number. Need to show my work.
9.86 would be 10
5.47 would be 5
10-5 would be 5
9.8
To round a decimal number to the nearest whole number, you need to look at the decimal part of the number. If the decimal part is less than 0.5, you round down to the nearest whole number. If the decimal part is 0.5 or greater, you round up to the nearest whole number.
Now let's use this concept to solve your problem:
1. Start with the given number: 9.86 - 5.47
2. Subtract 5.47 from 9.86: 9.86 - 5.47 = 4.39
3. Examine the decimal part of 4.39, which is 0.39.
4. Since 0.39 is less than 0.5, we round down to the nearest whole number.
5. Therefore, the result rounded to the nearest whole number is 4.
So, rounding 9.86 - 5.47 to the nearest whole number gives us the result of 4.
