Answer 3

It seems like you've provided a series of mathematical expressions and equations. Let's break down each part:

1. $\frac{2}{5} - \frac{4}{51} + \frac{370}{5} - \frac{1}{225} \frac{1}{5} - 6 \frac{1}{62}$

   This is a combination of fractions, whole numbers, and subtraction:

   $\frac{2}{5} - \frac{4}{51} + \frac{370}{5} - \frac{1}{225} - \frac{1}{5} - \frac{1}{62}$

   You can simplify the fractions and perform the arithmetic operations to get a single value.

2. $9 \cdot 4 \frac{1}{34} \cdot (-4.5) \frac{4}{0.4}$

   This is a combination of multiplication and fractions:

   $9 \cdot 4 + \frac{1}{34} \cdot (-4.5) \cdot \frac{4}{0.4}$

   Again, you can simplify the fractions and perform the arithmetic operations to get a single value.

If you provide the numerical values of the fractions and the intended operations (addition, subtraction, multiplication), I can help you calculate the results. Additionally, I noticed an issue with division by zero in the second expression ($\frac{4}{0.4}$). Division by zero is undefined in mathematics. Please double-check the expression for accuracy.
