The correct option is
A A = 2.8; B = 8
To find the correct values of A and B, we substitute the given values in the options into the equation A
÷ B = 0.35.
For first option:
Value of A = 2.8
Value of B = 4
∴ A
÷ B = 2.8
÷ 4
= 2.80
÷ 4
Calculating 2.80
÷ 4 using the standard method, we get:

So, 2.8
÷ 4 = 0.7
But, we know, 0.7
≠ 0.35
So, the first option does not show the correct values of A and B.
Next, for second option:
Value of A = 2.8
Value of B = 8
∴ A
÷ B = 2.8
÷ 8
= 2.80
÷ 8
Calculating 2.80
÷ 8 using the standard method, we get:

So, 2.8
÷ 8 = 0.35
This matches exactly with the values in the given equation.
Now, for the third option:
Value of A = 3.8
Value of B = 5
∴ A
÷ B = 3.8
÷ 5
= 3.80
÷ 5
Calculating 3.80
÷ 5 using the standard method, we get:

So, 3.80
÷ 5 = 0.76
But, we know, 0.76
≠ 0.35
So, the third option does not show the correct values of A and B.
Hence, the correct values of A and B are: A = 2.8; B = 8
