Answer 1

Answer:

45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ?

Step-by-step explanation:

Which equation shows one way to find the value of 45 × 4?

45 × 4

Splitting each number into factors of each other

45 = 9 × 5

4 = 2 × 2

45 × 4 = (9 × 5) × (2 × 2)

45 × 4 = (9 × 2) × (5 × 2)

45 × 4 = 18 × 10

Option A is the correct option
