Question

Eric estimated 28x48 by finding 30x50. His estimate was 1,500,but he says the actual product will be greater than that amount.Is he correct? Explain how you know

Answer 1

Answer:

Eric is not correct.

Step-by-step explanation:

We have been given that Eric estimated $28\times 48$ by finding $30\times 50$. His estimate was 1500, but he says the actual product will be greater than that amount.

To find if Eric is correct or not, let us see how to estimate an answer.

While estimating our given numbers we will round to nearest tenth and change the digit to the right of the rounding place to 0.

As 8 is greater than 5, so we will round 28 to 30 and 48 to 50.

Since we are rounding up, so our estimated answer will be greater than actual answer, therefore, Eric is not correct.
