Question #72d2a

Answer 1

See a solution process below:

Explanation:

`3.02 xx 10.6 = 32.012`

To write this number in scientific notation we need to move the decimal point one place to the left so the exponent for the 10s term will be positive:

`32.012 = 3.2012 xx 10^1` or `3.2012 xx 10`

`4.5 xx 105 = 472.5`

To write this number in scientific notation we need to move the decimal point two places to the left so the exponent for the 10s term will be positive:

`472.5 = 4.725 xx 10^2`

Answer 2

`8003/250`

Explanation:

`3.02*10.6`

`=302/100*106/10`

`=151/50*53/5`

`=8003/250`
