Mary bought a roll of ribbon.After using 5/8 of the ribbon to decorate some packages,she had 15ft of the ribbon left.How many feet of ribbon did she buy?
i hate math
Its 350 feet😚
To find out how many feet of ribbon Mary bought, we can subtract the length of ribbon she had left after decorating the packages from the length of ribbon she initially bought.
Given information:
- Length of ribbon left after using 5/8: 15 ft
Let's denote the length of the ribbon Mary initially bought as 'x'.
Now we know that 5/8 of the ribbon was used, which means she has (1 - 5/8) = 3/8 of the ribbon left.
We can set up the following equation to solve for 'x':
3/8 * x = 15
To solve for 'x', we can multiply both sides of the equation by the reciprocal of 3/8, which is 8/3:
x = (15) * (8/3)
Now, we can calculate the value of 'x':
x = 120/3
x = 40
Therefore, Mary bought 40 feet of ribbon.
Jan had 22 3/4 feet of ribbon. To make bows, she cuts it into pieces that are 1 2/3 feet long. How many bows will she be able to make?
1 1/4
8/8 - 5/8 = 3/8 Left.
3x/8 = 15,
3x = 120,
X = 40 Ft.
