A.7/8 YARDS
B.5/4
c.7 yards
D.21/8(i picked this)
------------------------
10.write 5 and 2 thirds as an improper fraction and as a mixed number.
A.7/5,2 3/5
B.13/5 , 2 3/5
C.15/3 , 5 2/3
D.17/3 , 5 2/3(i picked this)
Both are right.
thanks
You're welcome.
To check your answers for the math problems, let's go through each one step by step:
1. Sarah is making her own Halloween costume, and it requires 2 5/8 yards of materials. To write this as an improper fraction, you need to combine the whole number and the fraction. Here's how you can do it:
Start by multiplying the whole number (2) by the denominator of the fraction (8), and add the result to the numerator (5). This gives us: 2 * 8 + 5 = 16 + 5 = 21.
The resulting improper fraction is 21/8 (D), which means Sarah needs 21/8 yards of material for her Halloween costume.
2. The number 5 and 2/3 can be written as both an improper fraction and a mixed number.
To convert the mixed number to an improper fraction, multiply the whole number (5) by the denominator of the fraction (3) and add the numerator (2). This gives us: 5 * 3 + 2 = 15 + 2 = 17. The resulting improper fraction is 17/3.
To convert the improper fraction to a mixed number, divide the numerator (17) by the denominator (3). This will give you the whole number part. The remainder will be used as the numerator of the fraction. Dividing 17 by 3 gives you 5 with a remainder of 2. So the fraction part is 2/3.
Therefore, the answer is 17/3 as an improper fraction and 5 2/3 (D) as a mixed number.
It seems you got the same answer as I did for both questions. Well done! If you have any more math questions or need further assistance, feel free to ask.
