Question:
1.Russell has a pipe that is 150 inches long. it must be cut into 3 1/8 inches segments for project. How many segments will he have?
2. Rebeckah is an elementary school teacher. she is making an individual craft project kits that requires 2/3 of a cup of water to complete. How many cups of water will she needs if she is making the craft project kits for each of her 24 students?
3. To paint the walls of the new gym, Russell and Roger took measurements. based on their calculations, they determined they needed 361/3 gallons of paint. Change this number to a kix number.
4. A recipe from Oma's German cookbook for a scallopes potato tart requires 9 1/2 grams of grated cheese. How many grams of cheese would she need if she made one tart for each of her 14 grandchildren?
The first two problems have already been answered.
Now it's your turn.
I'll be glad to check your answers for 3 and 4.
Thanks Ms.Sue
1. To find the number of segments that Russell will have, you need to divide the total length of the pipe by the length of each segment. The pipe is 150 inches long and each segment is 3 1/8 inches long.
To divide fractions, you can convert the mixed number (3 1/8) into an improper fraction. Multiply the whole number (3) by the denominator (8), then add the numerator (1). This gives you 25/8.
Now you can divide. Divide the total length of the pipe (150) by the length of each segment (25/8).
150 ÷ (25/8) = 150 × (8/25) = 1200/25 = 48 segments
So Russell will have 48 segments.
2. To find the number of cups of water Rebeckah will need, you need to multiply the amount of water required for one craft project kit (2/3 cup) by the number of students (24).
To multiply fractions, simply multiply the numerators (2 × 24) and multiply the denominators (3 × 1).
(2/3) × 24 = (2 × 24)/(3 × 1) = 48/3 = 16 cups
So Rebeckah will need 16 cups of water for all 24 students.
3. To change the mixed number (361/3) into a mixed fraction, you need to divide the numerator (361) by the denominator (3). The quotient will be the whole number, and the remainder will be the new numerator.
Divide 361 by 3: 361 ÷ 3 = 120 with a remainder of 1.
So the mixed number 361/3 can be written as 120 1/3.
4. To find the total grams of cheese Oma would need, you need to multiply the amount of cheese required for one tart (9 1/2 grams) by the number of grandchildren (14).
To multiply a mixed number by a whole number, you need to convert the mixed number into an improper fraction. Multiply the whole number (9) by the denominator (2), then add the numerator (1). This gives you 19/2.
Multiply the improper fraction (19/2) by the number of grandchildren (14):
(19/2) × 14 = (19 × 14)/(2 × 1) = 266/2 = 133 grams
So Oma would need 133 grams of cheese for all 14 grandchildren.
