Question

Estimate how many times (6.1) x 10^7 is than (2.1) x 10^-4.

a) 290,476,190 times
b) 29,047,619 times
c) 2,904,762 times
d) 290,476 times

Answer 1

By dividing (6.1) x 10^7 by (2.1) x 10^-4, we get an estimation of 29,047,619 times, making option (b) the correct answer.

Step-by-step explanation:

To estimate how many times (6.1) x 10^7 is greater than (2.1) x 10^-4, we need to divide the two expressions. Using a calculator, we follow these steps:

1. Enter (6.1) x 10^7.
2. Press the divide (÷) button.
3. Enter (2.1) x 10^-4.
4. Press the equals (=) button.

The result will be approximately 2.9047619 x 10^11, which we can round to 29,047,619 times as an estimation.

To answer the student's question directly: (6.1) x 10^7 is estimated to be 29,047,619 times greater than (2.1) x 10^-4.

Therefore, the correct answer is option (b) 29,047,619 times.
