Question

Explain whether rounding or compatible numbers gives a closer estimate for the product 48 x 123= 5904.

Answer 1

Rounding off the number gave a better approximate of the product of given numbers.

Explanation:

We are given the following information:

`48* 123 = 5904`

Compatible numbers are the numbers that are easy to add, subtract and multiply.

Now, if we use compatible numbers to evaluate the same product we get:

`45* 120 = 5400`

Now, if we round off the given numbers, we can evaluate the product as:

`50* 120 = 6000`

Hence, rounding off the number gave a better approximate of the product of given numbers.
