Susan uses 15 rolls of ribbon to decorate 10 wedding baskets. Each roll of ribbon is 5 3/8 yards long. After she decorates the baskets, she decides to cut off another 3/4 yard from the ribbon of each basket. Write and simplify an expression to fin out how much ribbon was used on the baskets.
Please show work
r = ribbon = 15 (5 3/8) - 10(3/4)
r = 15 (43/8) - 60/8
r = (15*43 - 60 )/8 = 585/8 = 73 1/8 yards
TinaHas 3 ribbon measuring 18inches,24inches and 36 inches . She. Wants to cut them into equal pieces that are as long as possible. Into what Length should she cut the ribbon
To find out how much ribbon was used on the baskets, we can start by calculating the length of ribbon used for each basket.
Each roll of ribbon is 5 3/8 yards long, which can also be written as 5 + 3/8 = (40/8 + 3/8) = 43/8 yards.
Since Susan uses 15 rolls of ribbon, the total length of ribbon she starts with is 15 * (43/8) = 645/8 yards.
Next, Susan cuts off an additional 3/4 yard from each basket. Since there are 10 baskets, the total amount of ribbon cut off is 10 * 3/4 = 30/4 = 15/2 yards.
To find out how much ribbon was used on the baskets, we subtract the amount of ribbon cut off from the total length of ribbon. So the expression to determine the amount of ribbon used is: (645/8) - (15/2).
Now let's simplify this expression:
To subtract fractions, we need a common denominator. In this case, the least common denominator (LCD) is 8. So, we rewrite both fractions with a denominator of 8:
(645/8) - (15/2) = (645/8) - (120/8) = (645 - 120)/8 = 525/8.
Therefore, the simplified expression to find the amount of ribbon used on the baskets is 525/8 yards.
