Answer 3

To solve this expression, let's follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).

The expression you provided is: $7.8 \times \frac{4}{3} - \frac{61.5}{13} \div \frac{2.3}{198.8}$.

Let's solve it step by step:

1. First, let's simplify the fractions: $7.8 \times \frac{4}{3} = 10.4$ $\frac{61.5}{13} = 4.73$ $\frac{2.3}{198.8} \approx 0.0116$

2. Next, perform the division and multiplication operations: $10.4 - 4.73 \div 0.0116$

3. Now, divide $4.73$ by $0.0116$: $4.73 \div 0.0116 \approx 407.76$

4. Subtract the result from step 3 from $10.4$: $10.4 - 407.76 \approx -397.36$

So, the value of the given expression is approximately $-397.36$.
