the bulletin board in Shain's classroom is 3 1/4 feet by 4 1/2 feet.
what is the area of the bulletin board?
is this right? 24 1/2 ?
12 1/8
To find the area of the bulletin board, you need to multiply the length by the width.
The length is given as 3 1/4 feet, which can be written as a mixed number or an improper fraction. Converting it to an improper fraction, we get 13/4 feet.
The width is given as 4 1/2 feet, which can be written as a mixed number or an improper fraction. Converting it to an improper fraction, we get 9/2 feet.
Now, we can multiply the length and width to find the area:
(13/4) feet * (9/2) feet = (117/8) square feet
To simplify the fraction, we can divide the numerator by the denominator:
117 ÷ 8 = 14 remainder 5
Therefore, the area of the bulletin board is 14 5/8 square feet, not 24 1/2.
To find the area of the bulletin board, you need to multiply the length by the width. In this case, the length of the bulletin board is 3 1/4 feet and the width is 4 1/2 feet.
To multiply mixed numbers, you first need to convert them into improper fractions.
3 1/4 as an improper fraction is (3 x 4) + 1 = 13/4
4 1/2 as an improper fraction is (4 x 2) + 1 = 9/2
Now, multiply the fractions: (13/4) x (9/2)
To multiply fractions, you simply multiply the numerators (top numbers) and the denominators (bottom numbers):
(13 x 9) / (4 x 2) = 117/8
The area of the bulletin board is 117/8 square feet. Since this is an improper fraction, you can also express it as a mixed number by dividing the numerator by the denominator:
117 ÷ 8 = 14 remainder 5
So, the area of the bulletin board is 14 5/8 square feet.
Therefore, the answer is not 24 1/2. The correct area of the bulletin board is 14 5/8 square feet.
No.
Multiply 3 1/4 * 4 1/2
It's easier to change those mixed numbers to decimals and then multiply.
