One patern called for 2/3 of a yard of lace, and another pattern called for 5/9 of a yard of lace. In simplest form, how much more lace did the first pattern call for than the second?

2/3 = 6/9

6/9 - 5/9 = ???

The answer is 1/9.

To find out how much more lace the first pattern called for than the second, we need to subtract the amount of lace required by the second pattern from the amount required by the first pattern.

The first pattern called for 2/3 of a yard of lace.
The second pattern called for 5/9 of a yard of lace.

To subtract fractions, we need to have a common denominator. In this case, the least common denominator (LCD) of 3 and 9 is 9. We can convert both fractions to have a denominator of 9.

For the first pattern:
2/3 = (2/3) × (3/3) = 6/9

For the second pattern:
5/9

Now, we can subtract:
6/9 - 5/9 = (6 - 5)/9 = 1/9

Therefore, the first pattern called for 1/9 of a yard more lace than the second pattern.
