Question 4 :
Rebecca read 213 pages of a book on Saturday. On Sunday she read some more pages of the book. If Rebecca read 416 pages in all, how many pages did she read on Sunday ?
Solution :
Number of pages she read on Saturday = 213
Number of pages she read in all = 416
213 + Number of pages she read in Sunday = 416
Number of pages she read in Sunday = 416 - 213
= 203
Number of pages she read on Sunday is 203.
