Answer:

$\frac{1}{20}$ of a second

Step-by-step explanation:

We can convert each time into fractions.

11.74 is the same thing as $11 \frac{74}{100}$

and 11.69 is the same thing as $11 \frac{69}{100}$ .

We know that 11 - 11 = 0, so we can focus on the fractions for now.

Let's subtract $\frac{69}{100}$ from $\frac{74}{100}$ .

$\frac{74}{100} - \frac{69}{100} = \frac{5}{100}$ .

We can now simplify $\frac{5}{100}$ by dividing both the numerator and denominator by 5.

$\frac{5\div5}{100\div5} = \frac{1}{20}$ .

Hope this helped!

3 ( ( 3 (7) + ( 7 ( 7 ) ) )

3 ( ( (21) + (49) ) ) )
