Step-by-step explanation:
1) 12 x 3.14 = 36
2) 20/2 = 10
3) 12 x 2 x 3.14 = 72
4) 7 x 2 x 3.14 = 42
5) 36/3.14 = 12/2 = 6
6) 30 x 3.14 - 90
8) 11 x 2 =22
9) 9 x 2 x 3.14 = 54

Step-by-step explanation:
Answer:
1) 5/6 miles
2) 2 7/24 cups
Step-by-step explanation:
1) Convert each mixed number into an improper fraction.
1 ½ = (2×1+1)/2 = 3/2
2 ⅓ = (3×2+1)/3 = 7/3
To add or subtract, find the common denominator.
3/2 = 9/6
7/3 = 14/6
The difference is:
14/6 − 9/6 = 5/6
2) To add the fractions, first find the common denominator (least common multiple of the denominators). To do that, write the prime factorizations:
3 = 3
8 = 2³
4 = 2²
LCM = 2³ × 3 = 24
2/3 = 16/24
7/8 = 21/24
3/4 = 18/24
The sum is:
(16 + 21 + 18) / 24
55/24
To convert to a mixed number, divide the numerator by the denominator. 24 goes into 55 two times with a remainder of 7.
55/24 = 2 7/24
Answer:
17
Step-by-step explanation:
The number of students that liked one more than the other or didn't like either is 15 + 18 + 5, which is 38. The rest of the students in the class liked both subjects. 55 - 38 = 17.
