First, rewrite 9/20 and 7/15 so that they have a common denominator. Then, use <, =, or > to order
9/20 and 7/15
9/20 = ? ; 7/15 = ?
9/20 <,>, or = 7/15

5?

- mathstudent55

No. You misunderstood me.
You found a number that you can divide 15 by and 20 by with no remainder.
15/5 = 3, and 20/5 = 4. No remainder.
That's not what we need.
We need a number greater than 15 and 20. Call that number x.
The number must be such that x/15 and x/20 have no remainder.
Here's a way of finding such a number.
Multiply 15 by 1, 2, 3, 4, 5, and write down the numbers.
Then multiply 20 by 1, 2, 3, 4, 5, and write down the numbers.
The smallest number in both lists is the number we need.

60?

- mathstudent55

Excellent.
60 is the least common multiple of 15 and 20.
That means 60 is the smallest number that you can divide by both 15 and 20 with no remainder.

We are comparing these two fractions with denominators 15 and 20.
|dw:1440013066669:dw|

- mathstudent55

Now that we know that 60 is the least common denominator, we need to change both fractions to a denominator of 60.

- mathstudent55

To change a fraction to an equivalent fraction, we must multiply the numerator and denominator by the same number.

Now that we have equivalent fractions with the same denominator, 60, we can compare them with <, =, or >.

Wow, you answer my question before I even ask.

- mathstudent55

Since we use < in the equivalent fractions below, we use < also in the original fractions.
