$(0.05\times 6.25)÷2.5=?$

What will come in place of the question mark (?) in the following questions?

The correct option is 0.125.

Step-by-Step Explanation:

We are asked to find the value of the question mark (?) in the following expression:

$(0.05\times 6.25)÷2.5=?$

Step 1: Perform the multiplication inside the parentheses.

First, calculate the product of 0.05 and 6.25:

$0.05\times 6.25=0.3125$

Step 2: Perform the division.

Now, divide the result obtained in Step 1 by 2.5:

$0.3125÷2.5=\frac{0.3125}{2.5}$

To make the division easier, multiply both the numerator and the denominator by 10 to clear the decimal from the denominator:

$\frac{0.3125\times 10}{2.5\times 10}=\frac{3.125}{25}$

Now, divide 3.125 by 25:

$3.125÷25=0.125$

Therefore, the value that replaces the question mark (?) is 0.125.
