Answer 1

Answer:

12400; Property used: Distributive property

Step-by-step explanation:

Aim: To find solution using suitable property.

To solve this question, we must apply distributive property of multiplication over addition, i.e. (a × b) + (a × c) = a (b + c)

Now, the values of each variable according the question are:

a = 620

b = 15

c = 5

Applying property:

620 × 15 + 620 × 5 = 620 (15 + 5)

                                = 620 × 20

                                = 12400

Therefore, the solution is 12400.

Tip:

There are 2 types of distributive property of multiplication:

• Distributive property of multiplication over addition: (a × b) + (a × c) = a (b + c)
• Distributive property of multiplication over subtraction: (a × b) - (a × c) = a (b - c)
