In a class, there are 20 girls and 15 boys. Each child brings 5 books for donating to a charity home. Find the total number of books donated by the class.
We have,
Number of books donated by girls = 20 × 5
Number of books donated by boys = 15 x 5
Total number of books = (20 x 5) + (15 x 5)
= (20 + 15) * 5 (Distributive property)
= 175
Final answer:- Total number of books are 175.
