Here is the question: Use rounding to estimate the answer: 783 divided by 4. My answer is 195 is this right?
Using rounding, I'd divide 800 by 4 to estimate 200. Estimate is the key in this question.
If you used a calculator, then 783/4 = 195.75 = 196 rounded to the nearest whole number.
783/4 = 800/4 - 17/4 = 200 - 4 1/4
Round that off to 196
To use rounding to estimate the answer, you can follow these steps:
1. Look at the digit to the right of the rounding point, which in this case is the tenths place.
In the number 783, the digit to the right of the rounding point is 8.
2. If the digit is 5 or greater, round up by adding 1 to the rounding point.
If the digit is less than 5, round down by keeping the rounding point as it is.
In the case of 783 divided by 4, let's first round up to the nearest tenth:
The digit in the tenths place is 8, which is greater than 5. So, you would round up to 790.
Next, divide the rounded number by 4: 790 divided by 4 equals 197.5.
Therefore, the rounded estimate for 783 divided by 4 is 197.5, not 195.
Please note that rounding to a specific number of decimal places is important in this case. In this example, we rounded to one decimal place, but the actual answer contains a half, so it can be expressed as either 197 or rounded up to 198 if we need a whole number.
