Answer:
The answer is 269.7
Step-by-step explanation:
In order to determine the result of the problem, firstly, we need to know every notation of the position numbers in an integer number.
I have attached an image that shows some notations of the position numbers.
As we see in the image, the "tens" notation is relation to multiplicate the number by 10. Also, the "tenths" notation is relation to multiplicate the number by 0.1.
So, we have to determine the numbers of the subtraction:
30 tens=30*10=300
3 tens 3 tenths=3*10+3*0.1=30.3
30 tens- 3 tens 3 tenths=300-30.3=269.7
Finally, the number of the expression is 269.7
