Answer 2

Calculating the Value of the Expression 1/1/36-1/45

To find the value of the expression 1/1/36-1/45, we can start by simplifying the fractions and then performing the subtraction.

First, let's simplify the fractions: 1/1/36 can be rewritten as 1 / (1/36) = 1 / (1 ÷ 36) = 1 / 36 1/45 remains as 1/45

Now, we can subtract the simplified fractions: 1/36 - 1/45 = (1*45 - 1*36) / (36*45) = (45 - 36) / 1620 = 9 / 1620 = 1 / 180

So, the value of the expression 1/1/36-1/45 is 1/180.

Understanding the Difference in Solutions

You mentioned that you saw a solution where the answer was 20, but you are unsure why the solution using a common denominator is incorrect with the answer 180.

It's important to note that when dealing with fractions, the order of operations must be followed. In the expression 1/1/36-1/45, the division should be performed before the subtraction. This means that 1/1/36 should be evaluated as 1 / (1/36) before subtracting 1/45.

Let's verify this with the following calculation: 1/1/36-1/45 = 1 / (1/36) - 1/45 = 1 / (1 ÷ 36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1/36) - 1/45 = 1 / (1
