The product of 416 and 1.9 without using a calculator and rounding each number to one significant figure, you can follow these steps: 1. Round 416 to 1 significant figure: 416 becomes 400. 2. Round 1.9 to 1 significant figure: 1.9 becomes 2. Now, multiply the rounded numbers: 400 x 2 = 800. So, the estimated product of 416 and 1.9 is 800.

To estimate the product of 416 and 1.9 without using a calculator and rounding each number to one significant figure, you can follow these steps:

Round 416 to 1 significant figure: 416 becomes 400.

Round 1.9 to 1 significant figure: 1.9 becomes 2.

Now, multiply the rounded numbers: 400 x 2 = 800. So, the estimated product of 416 and 1.9 is 800.

Now, compare this estimate with Millie's answer of 7904. There seems to be a significant discrepancy between the two results. It's possible that Millie made an error in her calculation or that there might be a mistake in the provided information. You may want to double-check the values and calculations to ensure accuracy.

Final answer:

Millie's answer of 7904 to the calculation of 416x1.9 is not sensible. By rounding to one significant figure, the estimation of the product is 800, indicating an error in her calculation.

Step-by-step explanation:

Milie's calculator gave her the product of 416 times 1.9 as 7904, which seems incorrect. To estimate the product by rounding each number to one significant figure, we round 416 to 400 and 1.9 to 2.

Multiplying these estimated values gives us 400 times 2, which equals 800. Therefore, Millie's calculator answer of 7904 does not seem sensible.
