Answer 2

To solve the expression "4 19\14 : 2 3\5," we need to follow the order of operations, which is commonly remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Here's the step-by-step solution:

1. First, let's convert the mixed numbers into improper fractions: 4 19\14 = 4 + 19/14 = (4 * 14 + 19) / 14 = 63/14 2 3\5 = 2 + 3/5 = (2 * 5 + 3) / 5 = 13/5

2. Now, the expression becomes: (63/14) : (13/5)

3. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction: (63/14) * (5/13)

4. Multiply the numerators together and the denominators together: (63 * 5) / (14 * 13) = 315 / 182

The result of the expression "4 19\14 : 2 3\5" is 315/182.
