The correct option is
B 4
To find the tenths digit of A, we first have to calculate the value of A.
So, we calculate 34.23
÷ 3.
Now, 34.23
÷ 3 can be written as:

To calculate 1.23
÷ 3, we divide the model into 3 equal parts:

Hence, 1.23
÷ 3 = 0.41
Combining this with the initial equation, we get:
