Question

69 cents each. She used partial products to find the total cost in cents. Which are NOT possible partial products for 24 × 69? Choose all that apply. A. 24 B. 36 C. 180 D. 240

Answer 1

Answer:

A. 24  

Step-by-step explanation:

If we have two digits to multiply together, the multiplication of the individual digit of those number with each other whereby each digit retain its place is known as partial product.

From the given question, by applying the distributive property method, the partial products are:

24 × 69 = 24 × (60 + 9)  

open brackets

= (24 × 60) + (24 × 9)

By factorization

= 60 (20 + 4) + 9(20 + 4)

expanding the brackets, we get:

= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)

= 1200 + 240 + 180 + 36   (These are the partial products)

= 1656
