when would you use compatible numbers to estimate the value of an expresssion? explain

I wrote: You would compatible numbers that are easy to compute mentally when your looking for a quotient in a division problem.

is this answer ok?

Yes.

Your answer is partially correct. Compatible numbers can be used not only in division problems but also in other mathematical operations. Here's a more comprehensive explanation:

Compatible numbers are used to estimate the value of an expression when you want to quickly get an approximate answer without the need for precise calculations. These numbers are chosen to be close to the actual numbers in the problem, making mental calculations easier.

Compatible numbers are often used in division problems when you want to find a quotient. For example, if you were dividing 256 by 8, you could use compatible numbers by rounding both numbers to their nearest compatible numbers, such as 260 and 10. Then, you can mentally calculate that the quotient is approximately 26, based on the simplified numbers.

However, compatible numbers can also be used in addition, subtraction, and multiplication problems. In these cases, you would choose numbers that are easy to work with mentally and still give you a reasonable estimate. For example, in the expression 237 + 148, you could round both numbers to their nearest tens, which would be 240 and 150. Adding these compatible numbers would give you an estimate of 390.

In summary, compatible numbers are useful when you need to quickly estimate the value of an expression, regardless of whether it involves division, addition, subtraction, or multiplication.
