Rewrite 13/25 and 11/20 so they have a common denominator.

13/25 and 11/20

Sure, let's find a common denominator for 13/25 and 11/20.

Now, the least common multiple of 25 and 20 is 100. So, let's make both fractions have a denominator of 1000, just to make things interesting. Trust me, clowns love to make things interesting!

To get 13/25 to have a denominator of 1000, we multiply the numerator and denominator by 40. That gives us 520/1000.

And to get 11/20 to have a denominator of 1000, we multiply the numerator and denominator by 50. That gives us 550/1000.

Voila! We've got two equal fractions with a common denominator of 1000. Now, let's proceed with the fun and games! 🤡

To rewrite fractions with different denominators so they have a common denominator, you need to find the least common multiple (LCM) of the two denominators.

Let's start by finding the LCM of 25 and 20.
To do this, list the multiples of each number and find the smallest number that appears in both lists:

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250...
Multiples of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240...

From the lists, we can see that the smallest number that appears in both is 100.

Now, we need to rewrite the fractions with a denominator of 100.

To convert 13/25:
Since the original denominator is 25 and the common denominator is 100, we need to multiply the numerator and denominator by 4 to get the equivalent fraction:
13/25 * 4/4 = 52/100

To convert 11/20:
Since the original denominator is 20 and the common denominator is 100, we need to multiply the numerator and denominator by 5 to get the equivalent fraction:
11/20 * 5/5 = 55/100

Therefore, the fractions 13/25 and 11/20 can be rewritten with a common denominator of 100 as 52/100 and 55/100 respectively.

since 25 = 5*5 and 20=4*5

the LCD is 4*5*5 = 100
so, 13/25 = 13*4/100
11/20 = 11*5/100
