The first answer is wrong. The other two are correct.
To find the ratio of noncolor pages to color pages, we first need to determine the number of noncolor pages and color pages separately. We are given that for every 20 pages, 4 are in color. Therefore, we can calculate the number of noncolor pages by subtracting the number of color pages from the total number of pages.
Let's assume that the total number of pages is 20. Out of these 20 pages, 4 are in color and the remaining 16 are noncolor pages. So, the ratio of noncolor pages to color pages is 16:4.
Therefore, the correct answer is A. 20:4.
To find the ratio of "Ms" to all the letters in the word MATHEMATICS, we need to count the number of "Ms" and the total number of letters in the word.
Counting the number of "Ms" in MATHEMATICS, we find that there are 2 "Ms". The total number of letters in the word is 11.
So, the ratio of Ms to all the letters in the word MATHEMATICS is 2:11.
Therefore, the correct answer is B. 2/11.
To find the ratio of weekdays to all days in a week, we need to know the total number of weekdays and the total number of days in a week.
A week usually consists of 7 days, out of which 5 days are considered weekdays.
So, the ratio of weekdays to all days in a week is 5:7.
Therefore, the correct answer is D. 5 to 7.
