Compare: 3/4 5/6

Explanation
The fraction 3/4 is smaller than the fraction 5/6. This can be determined by comparing the numerators (3 and 5) and denominators (4 and 6) of the fractions. In this case, the numerator of the first fraction is smaller than the numerator of the second fraction, while the denominators are the same. Therefore, the first fraction is smaller than the second fraction.

Compare 3/4 3/8

Explanation
The fraction 3/4 is greater than the fraction 3/8. This is because the numerator (3) is the same in both fractions, but the denominator (4) is greater than the denominator (8). Since the denominator represents the number of equal parts the whole is divided into, a larger denominator means each part is smaller. Therefore, the fraction with the larger denominator has smaller parts and is greater in value.

B.

14/21
C.

Both

Correct Answer
C. Both

Explanation
Both 6/9 and 14/21 are equivalent fractions to 2/3. To find equivalent fractions, we can multiply or divide both the numerator and denominator by the same non-zero number. In this case, we can multiply 2/3 by 2 to get 4/6, and then multiply again by 3 to get 6/9. Similarly, we can multiply 2/3 by 7 to get 14/21. Therefore, both 6/9 and 14/21 are equivalent fractions to 2/3.

Simplify There are 24 students in Mrs. Nantz's class. Six of the students walk to school every day. What fraction of the students do not walk to school;?write in simplest form.

Correct Answer
3/4

Explanation
To find the fraction of students who do not walk to school, we need to subtract the fraction of students who walk to school from 1 (since all the students fall into either of the two categories - walking or not walking). Since 6 out of 24 students walk to school, the fraction of students who walk is 6/24. Subtracting this from 1, we get 18/24. Simplifying this fraction, we get 3/4. Therefore, 3/4 is the fraction of students who do not walk to school.
