So, the other side is 7.48 yards.
Answer:
In 180 days the three of them will do their laundry again on the same day.
Step-by-step explanation:
we need to find the least common factor or 9, 10 and 12:
LCM(9, 10, 12) = 180
7.47/3 = 2.49
1 yard = 2.49
2 x 2.49 =
4.98 is how much it will cost for 2 extra yards
