Question

3,6 + 2,7 m - 4 8/15 + n - 3 3/5 - m

Answer 1

$3,6 + 2,7m - 4\frac{8}{15} + n - 3\frac{3}{5} - m$

$\frac{18}{5} + 2,7m - 4\frac{8}{15} + n - 3\frac{3}{5} - m$

$\frac{18}{5} + 2,7m - \frac{68}{15} + n - 3\frac{3}{5} - m$

$\frac{18}{5} + 2,7m - \frac{68}{15} + n - \frac{18}{5} - m$

$2,7m - \frac{68}{15} + n - m$

$1,7m - \frac{68}{15} + n$

Answer 2

Let's simplify the expression step by step:

1. Add the numbers with the same variable (m): 3.6m - m = 2.6m

2. Add the numbers without variables: 2.7 - 4 8/15 - 3 3/5 = 2.7 - 4 8/15 - 3 3/5

To simplify the mixed numbers, you can convert them to improper fractions:

• 2.7 = -27/10
• 4 8/15 = -4 8/15 = -4 - 8/15 = -4 - (8/15)
• 3 3/5 = -3 3/5 = -3 - 3/5 = -3 - (3/5)

Now, combine the fractions:

• 27/10 - 8/15 - 3/5 = -27/10 - 8/15 - 3/5

To add these fractions, you need a common denominator, which is 30. So, you'll need to adjust the fractions accordingly:

• (27/10) * (3/3) = -81/30
• (8/15) * (2/2) = -16/30
• (3/5) * (6/6) = -18/30

Now that all the fractions have a common denominator, you can add them:

-81/30 - 16/30 - 18/30 = (-81 - 16 - 18) / 30 = -115/30

3. Now, combine the terms with variables and the constants: 2.6m - 115/30 + n

So, the simplified expression is: 2.6m - 115/30 + n
