A book store has a total stock of 19 books of 5th, 6th, 7th and 8th grades.
The table shows the number of books of each grade. Find the number of books of 5th grade.
Step 1: Number of books in 5th grade = Total number of books - Total number of books in 6th, 7th and 8th grades
Step 2: Total number of books of 6th, 7th and 8th grades = 3 + 3 + 5 = 11[Add the number of books of the three grades.]
Step 3: Number of books of 5th grade = 19 - 11 = 8[Substitute and subtract.]
