2. Jane is making a suit which requires 2 5/8 yards for the jacket and 1 3/4 yards for the skirt. What is the total amount of material she needs?
A. 4 3/8 yards
B. 3 2/3 yards
C. 4 yards
D. 3 1/2 yards
A?
3. Which one of the following pairs of numbers contains like fractions?
A. 6/7 and 60/70
B. 1/2 and 3/2
C. 4/8 and 12/16
D. 5/4 and 4/5
A?
both correct!
8. 7/8 = ?/48
A. 13
B. 42
C. 1
D. 6
I think it is B because
48 divided 8 = 6
and that means 7 * 6 = 42
right again.
To calculate the total amount of material Jane needs, we need to add the yardage for the jacket and the skirt.
The jacket requires 2 5/8 yards, which we can convert to an improper fraction as (2 * 8 + 5)/8 = 21/8 yards.
The skirt requires 1 3/4 yards, which can also be converted to an improper fraction as (1 * 4 + 3)/4 = 7/4 yards.
To add these fractions, we need a common denominator, which is 8. So we multiply the numerator and denominator of 7/4 by 2 to get 14/8 yards.
Now we can add the two fractions: 21/8 + 14/8 = 35/8 yards.
To convert this improper fraction back to a mixed number, we divide the numerator by the denominator:
35 divided by 8 equals 4 with a remainder of 3.
Therefore, the total amount of material Jane needs is 4 3/8 yards.
So, the correct answer is A.
