question

Pick the expression with the better compatible numbers to estimate

1,446

1,500

1,200

Now, use the expression you picked to estimate the quotient.

1,446

is about

key idea

Compatible numbers are pairs of numbers you can add, subtract, multiply, or divide easily in your head.

solution

You want to find the best compatible numbers for estimating

1,446

So, find a number close to 1,446 that can be easily divided by 3.

1,500 is close to 1,446 and can be easily divided by 3. You can use place value and the basic fact

to find the quotient:

1,500

500

So,

1,500

is a good way to estimate

1,446

The quotient is about

500.

The other expression,

1,200

isn't as good for estimating

1,446

The number 1,200 is not as close to 1,446 as 1,500 is.
