she would have 4/8 left and that how much she will have
A.
5 7/9 yards
B.
5 5/9 yards
C.
5 5/3 yards
D.
5 1/3 yards
Casey bought a total of 5 5/9 yards of fabric (yellow and purple combined). The pair of scissors does not count towards the total yardage of fabric.
The first step is to add the amount of yellow and purple fabric that Casey bought. So we have 2 2/3 yards of yellow and 3 1/9 yards of purple fabric, which gives us a total of 5 5/9 yards of fabric (Since 2 2/3 equals 8/3 and 3 1/9 equals 28/9, when we add them we have 8/3 + 28/9 = 56/27, which simplifies to 5 5/9). The pair of scissors does not count towards the amount of fabric bought, so it can be disregarded for this question. Thus, the correct answer is B. 5 5/9 yards.

2) I'm using r for rate .If it's 60km in 4h that means that 1/4=r/60 which means you can cross multiply it and it'd be 60=4r. If you divide 4 on both sides it would be 15=r. The rate is 15km and hour.
3) For this one, it's the same. You have to put 1/12=r/24 and cross multiply. It would be 24=12r then you divide both sides by 12 and you get 2=r.
4) It says d=r*t. For this problem, d=56 and r=8 if you substitute it you would have 56=8t and if you divide both sides by 8 you would have 7=t.
5) d=r*t. This means that if you substitute it, you would have d=25*160. 25*160=4000 so d=4000
