Answer 1

To find the total amount of lace trim needed, add the amounts for the dress and veil together. The pattern calls for 20 1/4 yards of lace trim.

Step-by-step explanation:

To find the total amount of lace trim needed, you need to add the amounts for the dress and veil together. The dress requires 12 4/5 yards of lace trim, and the veil requires 8 1/4 yards of lace trim.

To add fractions, you need to have a common denominator. In this case, the common denominator is 20. Multiply the denominator by the whole number and add the numerator to get the new fraction. For the dress: 12 x 20 + 4 = 244/20. For the veil: 8 x 20 + 1 = 161/20.

Now, add the fractions together: 244/20 + 161/20 = 405/20. Reduce this fraction by dividing the numerator and denominator by their greatest common factor, which is 5. 405/20 ÷ 5/5 = 81/4. This is equal to 20 1/4. Therefore, the pattern calls for 20 1/4 yards of lace trim.
