How do I estimate 791 divided by 38 and use compatible numbers if necessary
800 / 40 =
To estimate and divide 791 by 38 using compatible numbers, follow these steps:
Step 1: Identify compatible numbers
Compatible numbers are close to the original numbers and easy to work with. Look for numbers that are multiples of 10, 100, or 1000.
In this case, compatible numbers near 791 could be 800 or 750, while 38 can approximate to 40 or 30.
Step 2: Choose compatible numbers
For simplicity, let's choose 800 for 791 and 40 for 38.
Step 3: Divide the compatible numbers
Divide 800 by 40: 800 ÷ 40 = 20.
Step 4: Divide the original numbers
Divide 791 by 38: 791 ÷ 38 ≈ 20.
Using compatible numbers, we estimate that 791 divided by 38 is approximately 20.
To estimate the division of 791 by 38 and use compatible numbers if necessary, you can follow these steps:
1. Identify the compatible numbers: Compatible numbers are numbers that are close to the original numbers and are easy to work with. In this case, you can consider 40 as a compatible number for 38 since it is the closest multiple of 10.
2. Adjust the dividend: Start by adjusting the dividend (791) to make it more compatible. Since 791 is closer to 800 than it is to 790, you can round it up to 800.
3. Adjust the divisor: Similarly, round the divisor (38) to its compatible number, which is 40.
4. Divide the adjusted dividend by the adjusted divisor: Now, divide the adjusted dividend (800) by the adjusted divisor (40). The result is 20.
Therefore, by estimating with compatible numbers, you can estimate that 791 divided by 38 is approximately equal to 20.
