Brett asked 20 students in his class which breakfast cereal they prefer. The table shows the results
Frosties 12 students
Crispy Kicks 5 students
Berry Pops 3 students
What decimal represents the fraction of students who prefer Crispy Kicks?
.20
Both your answers are wrong.
Second one is .25
For the first one the answer is 65 9/8 but 9/8 is improper so would I divide
Yes and yes.
Change 9/8 to a mixed fraction.

The mixed fraction would be 1 1/8?
The answer would be A?
Right.
To find out how tall Marcus is, we first need to add the height difference between Marcus and Rolando to Rolando's height.
Marcus is 4 5/8 inches taller than Rolando, so we need to add 4 5/8 to 61 1/2.
To add mixed numbers, we first convert them into improper fractions.
61 1/2 = (2 * 61 + 1) / 2 = 123/2
4 5/8 = (8 * 4 + 5) / 8 = 37/8
Now, we can add the fractions:
123/2 + 37/8
To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 2 and 8 is 8.
123/2 = 492/8
Now, we can add the fractions:
492/8 + 37/8 = (492 + 37) / 8 = 529/8
To convert the improper fraction back to a mixed number, we divide the numerator (529) by the denominator (8) and write the quotient as the whole number part. The remainder becomes the numerator of the fraction.
529 ÷ 8 = 66 remainder 1
So, Marcus is 66 1/8 inches tall.
Therefore, the correct answer is A. 66 1/8 in.
