Answer:
121.021
Step-by-step explanation:
Well the word “and” indicates the decimal so we know the whole number is 121.
Now for decimals it goes in the order of tenths, hundredths, thousandths, etc.
We have 21 thousandths
it would end up looking like this
121.021
The 0 is relevant due to the the fact the decimal is suppose to be 21 thousandths.
