Question

Multiply. Then check your work by switching factors. (I know how to multiply but can someone help with switching factors)

A) 693x83 =57,519
B) 910x 45= 40,950
C) 38x84= 3,192
D) 409x89= 36,401

Answer 1

Answer: The answers are given below.

Step-by-step explanation:

(1) The first product is 693 × 83 = 57,519.

This can also be written as

231 × 949 = 57,519 or 77 × 2847 = 57,519.

(2) The second product is 910 x 45= 40,950.

This can also be written as

455 × 90 = 40,950 or 91 × 450 = 40,950 or 182 × 225 = 40,950.

(3) The third product is 38 x 84= 3,192.

This can also be written as

19 × 168 = 3,192 or 76 × 42 = 3,192 or 152 × 21 = 3,192.

(4) The fourth product is 409 x 89= 36,401.

We cannot switch the factors here, because both 89 and 409 are prime numbers.

Thus, the answer is completed.
