Question: Melody needs to read 20 pages for her English class, 16 pages for her Science class, 8 pages for her Civics, and 12 pages for Chinese class. She decided to read one-fourth of the number of pages for each class tomorrow. How many pages will she read tomorrow?
Answer with step-by-step thinking:
She will read 20 pages / 4 = 5 pages for English. She will read 16 pages / 4 = 4 pages for Science. She will read 8 pages / 4 = 2 pages for Civics. She will read 12 pages / 4 = 3 pages for Chinese. Melody will read a total of 5 pages + 4 pages + 2 pages + 3 pages = 14 pages tomorrow.
So the answer is 14.
