Trisha needs 4 1/2 yards of fabric to do a project. if she already has 2/3 of a yard of fabric, what is the minimum amount of fabric she must buy to be able t complete her project

Subtract 2/3 from 4 and 1/2

first turn 4 and 1/2 into a fraction

2/2 = 1 so 4 = 8/2 + 1/2 = 9/2

now you have 9/2-2/3

 now find lowest common denominator ( 2*3 =6)

9/2 becomes 27/6

2/3 becomes 4/6

now you have 27/6 - 4/6 = 23/6

 6/6 = 1

6*3=18, 23-18 = 5

so she needs 3 and 5/6 yards of fabric

Letter b hope it
