To convert the fraction 45/90 to have a denominator of 36, you need to find an equivalent fraction with the desired denominator. Since 36 is not a multiple of 90, you'll need to adjust both the numerator and the denominator.

Here's how you can do it:

Step 1: Find the common factor between 90 and 36. Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

The common factor between 90 and 36 is 18.

Step 2: Divide both the numerator and the denominator of the fraction 45/90 by the common factor (18). (45 ÷ 18) / (90 ÷ 18) = 5/10

Step 3: Simplify the fraction, if possible. The numerator and the denominator share a common factor of 5, so you can divide them by 5 to simplify the fraction further. (5 ÷ 5) / (10 ÷ 5) = 1/2

So, the fraction 45/90, when simplified to have a denominator of 36, is equal to 1/2.
