Julie is making bookmarks for the 5th grade class. She has a roll of ribbon 6 feet long. Each bookmark requires 4 3/4 inches of ribbon. how many complete bookmarks can she make?
Just divide 6 feet by 4 3/4 inches and round down
15 with some ribbon left over
To find out how many complete bookmarks Julie can make, we need to first convert the length of the ribbon roll to inches. Since there are 12 inches in 1 foot, we can multiply 6 (feet) by 12 (inches per foot). This will give us the total length of the ribbon in inches: 6 feet * 12 inches/foot = 72 inches.
Now, we need to determine how many bookmarks Julie can make with the given length of ribbon. Each bookmark requires 4 3/4 inches of ribbon. To figure out how many bookmarks can be made, divide the total length of the ribbon by the length needed for each bookmark.
Let's convert the length needed for each bookmark to a proper fraction: 4 3/4 inches = (4 * 4) + 3/4 = 19/4 inches.
Now, we can divide the total length of the ribbon (72 inches) by the length needed for each bookmark (19/4 inches) to find the number of complete bookmarks Julie can make: 72 inches ÷ (19/4 inches).
To divide by a fraction, we need to multiply by the reciprocal of that fraction. So, we can rewrite the division as multiplication: 72 inches * (4/19 inches).
Now, perform the multiplication: 72 inches * (4/19 inches) = 288/19 inches.
Since we want to find the number of complete bookmarks, we need to find how many times the length needed for each bookmark fits into the total length of the ribbon, without any remainder.
To do this, divide the numerator by the denominator: 288 ÷ 19 = 15 remainder 3.
This means that Julie can make 15 complete bookmarks using the entire roll of ribbon, with 3 inches remaining.
