What are the Multiples of 40?
To get multiples of a number we need to multiply natural numbers with integers. A multiple is a product of a number with another number. If X is a multiple of a and b, it means a × b = X. Here a & b are the natural numbers and X is the resultant multiple. Below are few examples to justify the above definition mathematically. For example, 4 × 9 = 36, 36 is a multiple of 9 and 4.
Now consider,
 40 × 1 = 40
 40 × 2 = 80
 40 × 3 = 120
 40 × 4 = 160
Do you observe that the multiples of 40 have a pattern of addition hidden? Yes, here you learned another method to find multiples, i.e., the addition of a number. According to this, the first five multiples you just learned are 40, 80, 120, 160 and 200.
Important Notes:
 The first multiple of every number is the number itself, 40 × 1 = 40.
 The multiples of a number are an infinite chain.
 Every multiple of a number is greater than or equal to the number itself.
 Multiples of an even number are always even.

Solved Examples on Multiples of 40

Example 1: If a restaurant sold 40 pizzas every day then how many pizzas will be sold by the restaurant in 30 days?
Solution:
Number of pizzas sold in 1 day = 40
Therefore, the number of pizzas sold in 30 days = 40 × 30 = 1200
Hence, restaurant will sell 1200 pizzas in 30 days. 
Example 2: Evaluate 40 times 12  40 times 7 using multiples of 20.
Solution:
Mathematically, 40 times 12  40 times 7 = 40 × 12  40 × 7
40 × 12  40 × 7 = 480  280 = 200
