Answer 3

To solve these multiplication problems involving mixed numbers, we can follow these steps:

1. Convert the mixed numbers into improper fractions.
2. Multiply the fractions.
3. Simplify the result, if possible, by reducing it to its simplest form or converting it back to a mixed number.

Let's solve the given problems step by step:

1. 1/7 × 2 1/3:

To convert 2 1/3 into an improper fraction: 2 1/3 = (2 × 3 + 1) / 3 = 7/3

Now we can multiply the fractions: 1/7 × 7/3 = (1 × 7) / (7 × 3) = 7/21

So, 1/7 × 2 1/3 = 7/21.

2. 2 2/5 × 5/6:

To convert 2 2/5 into an improper fraction: 2 2/5 = (2 × 5 + 2) / 5 = 12/5

Now we can multiply the fractions: 12/5 × 5/6 = (12 × 5) / (5 × 6) = 60/30

Simplifying the result, we can reduce 60/30 by dividing both the numerator and denominator by their greatest common divisor, which is 10: 60/30 = (60 ÷ 10) / (30 ÷ 10) = 6/3

Since 6/3 can be simplified further by dividing both the numerator and denominator by 3, we have: 6/3 = (6 ÷ 3) / (3 ÷ 3) = 2/1 = 2

So, 2 2/5 × 5/6 = 2.

Therefore, the final result is: 1/7 × 2 1/3 = 7/21 2 2/5 × 5/6 = 2
