To simplify the multiplication problem 3 1/2 x 2 2/7, you can follow these steps:

Step 1: Convert the mixed fractions to improper fractions.
- To convert 3 1/2 to an improper fraction, multiply the whole number (3) by the denominator (2) and add the numerator (1). So, 3 1/2 as an improper fraction is (3*2 + 1) / 2 = 7/2.
- Similarly, to convert 2 2/7 to an improper fraction, multiply the whole number (2) by the denominator (7) and add the numerator (2). So, 2 2/7 as an improper fraction is (2*7 + 2) / 7 = 16/7.

Step 2: Multiply the two improper fractions.
- To multiply fractions, multiply the numerators together and multiply the denominators together. So, (7/2) * (16/7) = (7*16) / (2*7) = 112/14.

Step 3: Simplify the resulting fraction.
- To simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator and divide both of them by the GCD.
- In this case, the GCD of 112 and 14 is 14. So, dividing both the numerator and the denominator by 14 gives us the simplified fraction: 112/14 = 8.

Therefore, the simplified product of 3 1/2 and 2 2/7 is equal to 8.
