4/5 + 2/3 = 3*4 / 3*5 + 5*2 / 5*3
= 12/15 + 10/15
= 22/15
[which is 1 7/15 if we care]
22/15 - 1/3 - (17/30)(2/3)
= 22/15 - 5/15 - 17/(3*15)
= 66/45 - 15/45 -17/45
= (66 - 32)/45
= 34/45

Assuming no typos,
4/5 + 2/3 = 12/15 + 10/15 = 22/15 = 1 7/15 yd total
She used 1/3 + 17/30 * 2/3 = 30/90 + 54/90 = 84/90 = 14/15 yds
So she had 8/15 yd left
4/5 + 2/3 = 12/15 + 10/15 = 22/15 = 1 7/15 yd total
She used 1/3 + 17/30 * 2/3 = 30/90 + 54/90 = 84/90 = 14/15 yds
So she had 8/15 yd left
