Answer 1

3 + 2/5 - 25/7 = (4/5 - 1/7 * 2/5) / 25/3

First, let's simplify the expression step by step.

3 + 2/5 can be written as 3 + 0.4 which equals 3.4

Next, 25/7 can be written as 3.5714 (rounded to 4 decimal places)

So, the expression becomes 3.4 - 3.5714 = -0.1714

Now, let's simplify the right side of the equation.

First, solve the expression inside the parentheses: 4/5 - 1/7 * 2/5 = 4/5 - 2/35 = 28/35 - 2/35 = 26/35 = 0.7429 (rounded to 4 decimal places)

Now, we have (0.7429) / 25/3 This can be written as (0.7429) * 3/25 = 0.0891 (rounded to 4 decimal places)

So, the final result is -0.1714 = 0.0891

Therefore, the solution to the given equation is -0.1714 = 0.0891.
