Final answer:
The fractions given for the number of siblings students at Carter junior high school have are converted to decimal form with appropriate rounding. The results are 0.0667 for no siblings, 0.1667 for three siblings, 0.333 for one sibling, and 0.417 for two siblings.
Step-by-step explanation:
To answer the student's question, we need to convert the given fractions into decimal form. Here are the step-by-step explanations for the conversions requested:
- a. To express the fraction of students with no siblings (1/15) as a decimal, divide the numerator (1) by the denominator (15). This gives us 0.0667.
- b. The decimal equivalent for the fraction of students with three siblings (1/6) is found by dividing 1 by 6, resulting in 0.1667.
- c. To write the fraction of students with one sibling (1/3) as a decimal, divide 1 by 3. The resulting decimal, rounded to the nearest thousandth, is 0.333.
- d. For the fraction of students with two siblings (5/12), divide 5 by 12. When rounded to the nearest thousandth, this gives us a decimal of 0.417.
As collaborative exercise suggestions in your class, you could conduct a survey on how many siblings each student has, create a frequency table, and then calculate the relative frequency and cumulative relative frequency for various sibling counts, ultimately discussing what percentage of students have different ranges of siblings.
