7/72 * 36/7 = 1/72 * 36 = 36/72 = 12/24= 1/2

Answer 3

To solve the expression, let's break it down step by step:

First, let's simplify the division:

7 / 72 = 0.097222222...

Now, let's multiply the result by 5:

0.097222222... * 5 = 0.486111111...

Next, let's convert the decimal back into a mixed number:

0.486111111... = 5/10 + 1/90 + 1/810 + ...

To find the fractional part, we can use the formula for an infinite geometric series:

S = a / (1 - r),

where S is the sum of the series, a is the first term, and r is the common ratio. In this case, a = 1/90 and r = 1/10.

S = (1/90) / (1 - 1/10) = (1/90) / (9/10) = (1/90) * (10/9) = 1/81

So, the fractional part is 1/81.

Putting it all together, the final result is:

5 + 1/81 = 5 1/81
