## What are some examples of compatible numbers?

Some examples of compatible numbers when doing division are 400 and 10, 36 and 6, 2400 and 12, and 64 and 8. 2400 and 12 are compatible because when doing this division (2400/12), we can quickly divide 24 by 12 to get 2 and put two zeros at the end to get 200.

### What are compatible numbers?

In mathematics, compatible numbers are the numbers that are easy to add, subtract, multiply, or divide mentally. Compatible numbers are close in value to the actual numbers that make estimating the answer and computing problems easier.

**What are compatible numbers 3rd grade?**

Compatible numbers are numbers that are easy to work with mentally, such as parts of 10. By third grade, students can also quickly answer 80 + 20 or 100 – 20 by recognizing compatible numbers.

**What does it mean to use compatible numbers to estimate the quotient?**

Compatible numbers are numbers that are close to the numbers they’re replacing that divide evenly into each other. The quotient is the result you get when you divide. 56,000 is pretty close to 55,304. 800 is pretty close to 875, AND it divides evenly into 56,000.

## What’s the difference between rounding and compatible numbers?

### What is the difference between rounding and compatible numbers?

**How do you estimate the quotient in division?**

To estimate the quotient, we first round off the divisor and the dividend to the nearest tens, hundreds, or thousands and then divide the rounded numbers. In a division sum, when the divisor is made up of 2 digits or more than 2 digits, it helps if we first estimate the quotient and then try to find the actual number.

**Which is the best definition of compatible numbers?**
