@ms.sue
i thought 1.was 1/2 so if you say noone of these then cant i put 0??
29/59 = appr .4915.. or about 1/2
thank you
Matt, yes 1/2 is correct
1/2}??
1. To find the answer, we need to calculate the ratio of students who have participated in dance class before to the total number of students in Rosalie's class.
We are given that 29 out of 59 students have participated in dance class before. To calculate the ratio, we divide the number of students who have participated by the total number of students:
29/59 ≈ 0.4915
Since we are asked for an approximate answer, we can round the decimal to the nearest whole number. In this case, 0.5 is closer to 1 than it is to 0. Therefore, the answer is approximately 1. So, the correct answer is C.1.
2. To determine which number does not round to the same number as the others, we need to round each number to the nearest whole number.
5 1/5 is already a whole number, so it rounds to itself.
4 5/6 is between 4 and 5, but it is closer to 5. Therefore, it rounds to 5.
5 6/7 is between 5 and 6, but it is closer to 6. Therefore, it rounds to 6.
4 11/12 is between 4 and 5, but it is closer to 5. Therefore, it rounds to 5.
From the given options, 5 1/5 (A) rounds to itself while the other numbers (B, C, D) round to 5. Therefore, the answer is A. 5 1/5.
