Question

Find which multiplication of sums will make the multiplication easier:

(2 × 4 × 9 × 25)
a) (18 × 29)
b) (3 × 6 × 12 × 25)
c) (9 × 25 × 30)
d) (4 × 9 × 25 × 50)

Answer 1

To make the multiplication of sums easier, you want to find an option that allows you to simplify the multiplication. Option b) (3 × 6 × 12 × 25) is the correct option as it allows us to cancel out one term and make the multiplication easier.

Step-by-step explanation:

To make the multiplication of sums easier, you want to find an option that allows you to simplify the multiplication. Let's analyze the given options:

a) (18 × 29): This multiplication does not include any of the original numbers in (2 × 4 × 9 × 25), so it does not make the multiplication easier.

b) (3 × 6 × 12 × 25): This multiplication includes the number 25 from the original multiplication, which allows us to cancel out one term. So this option makes the multiplication easier.

c) (9 × 25 × 30): This multiplication includes all the numbers from the original multiplication, so it does not simplify the multiplication.

d) (4 × 9 × 25 × 50): This multiplication includes all the numbers from the original multiplication, so it does not simplify the multiplication.

Therefore, the correct option is b) (3 × 6 × 12 × 25), as it allows us to cancel out one term and make the multiplication easier.
