Answer:
4.0109
Step-by-step explanation:
4×1+1×1/100+9×1/1000
Let's ensure that we did not miss any steps
Let's start
4×1=4
1×1/100=0.01
9×1/1000=0.0009
So back to the question
4+0.01+0.0009
4.0109
Depending on the question,they may ask you to leave your in one decimal place or two decimal place
So we will have
4.01 for 2 decimal place
4.0 for 1 decimal place
But since we are not given any condition to leave our answer then the final answer is 4.0109
