14.In a bag there are 2 red buttons, 3 green buttons, and 4 purple buttons. A student writes the ratio for the number of purple buttons to green buttons as 3:4. Is this student correct? Explain why or why not.
No, the student is not correct. The student correctly writes the ratio as 3:4 for the number of purple buttons to green buttons. However, according to the given information, there are actually 4 purple buttons and 3 green buttons, not the other way around.
The correct ratio for the number of purple buttons to green buttons would be 4:3

14. No, the student is not correct. The correct ratio is 4:3.
1. The question asks for the ratio of balls hit to left field to balls hit to right field. To find this ratio, we need to divide the number of balls hit to left field by the number of balls hit to right field. So, the ratio is 7/8. When you divide 7 by 8, you get 0.875. Rounded to the nearest hundredth, the ratio is 0.88, which is the correct answer.
2. The question asks for the part-to-whole ratio for the 6th-grade average of 79-70. To find this ratio, we need to take the number of students in the 79-70 range (27) and divide it by the total number of students (124). So, the ratio is 27:124, which is the correct answer.
3. The question asks what value should be inserted into each rectangle in the tape diagram. Based on the given information, the ratio of tickets sold to unsold tickets is 5:3. Since there are 1,200 tickets in total, we can divide it into 8 equal parts (5 parts for tickets sold and 3 parts for tickets not sold). Each part represents 1/8 of 1,200, which is 150. So, the value that should be inserted into each rectangle is 150.
4. The question asks how much Olivia gets if Sylvia gets $21 and their allowances are in the ratio 2:3. To find this, we can set up a proportion: 2/3 = x/$21. Solving for x, we get x = $14. So Olivia gets $14, which is the correct answer.
5. The question asks for an equivalent part-to-part ratio. Since the number of lower-level tickets sold is 106 and the number of upper-level tickets sold is 105, the equivalent part-to-part ratio would be 106:105, which is the correct answer.
6. The question asks for an equivalent part-to-part-to-whole ratio. From the given ratio table, we can see that the total number of quarts of red and yellow paint is 5 and the corresponding values are 3 and 2 respectively. So, the equivalent part-to-part-to-whole ratio would be 3:2:5, which is the correct answer.
7. The question asks how many parts of vinegar are needed if there are 6 parts of baking soda, given that the ratio of vinegar to baking soda is 3 to 1. Since the ratio is 3:1, we can set up a proportion: 3/1 = x/6. Solving for x, we get x = 18. So, 18 parts of vinegar are needed, which is the correct answer.
8. To convert 0.4 to a simplified fraction, we can write it as 4/10. Then, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2. Simplifying, we get 2/5. So, 0.4 is equivalent to 2/5, which is the correct answer.
9. The question asks for the percentage of Vinh's savings. To find this, we can divide Vinh's current savings of $160 by the cost of the standing mixer ($400) and then multiply by 100 to get the percentage. So, (160/400) * 100 = 40%. Vinh has saved 40% of the cost, which is the correct answer.
10. The question asks which choice would be best represented with percentages. Since percentages are useful for showing parts out of a whole, the most appropriate choice would be "what part of the vote each candidate received in an election." This choice involves comparing different parts (votes for each candidate) to the whole (total votes), making it suitable for representation using percentages.
11. The question asks what is equal to 37% of a meter. To find this, we can multiply 0.37 (the decimal form of 37%) by 100 (since percentages are out of 100) to get 37. So, 37% of a meter is equal to 0.37 meters.
12. The question asks how many students are left-handed if 5% of 840 students are left-handed. To find this, we can multiply 840 by 0.05 (the decimal form of 5%) to get 42. So, 42 students are left-handed, which is the correct answer.
13. The question asks for the percentage of rejected shoes. Since 3 out of every 200 pairs of shoes are rejected, we can divide 3 by 200 and then multiply by 100 to get the percentage. So, (3/200) * 100 = 1.5%. 1.5% of shoes are rejected, which is the correct answer.
14. The student is incorrect. According to the given information, there are 4 purple buttons and 3 green buttons. So, the correct ratio for the number of purple buttons to green buttons is 4:3, not 3:4.
