Question

((13 ⁄8 -15⁄ 12)-0,475)

Answer 1

((13/8-15/12)-0,475)=(39/24-30/24)-475/1000=9/24-19/40=45/120-57/120=-12/120= -1/10=-0,1

Answer 2

To solve this arithmetic expression, we can start by simplifying the fractions:

13/8 = 1 5/8 (we can divide 13 by 8 and get 1 with a remainder of 5, so the fraction is 1 and 5/8) 15/12 = 1 1/4 (we can divide both the numerator and the denominator by 3 and get 5/4)

So the expression becomes:

(1 5/8 - 1 1/4) - 0.475

We can further simplify the mixed numbers by finding a common denominator:

1 5/8 = 8/8 + 5/8 = 13/8 1 1/4 = 4/4 + 1/4 = 5/4

So the expression becomes:

(13/8 - 5/4) - 0.475

To subtract the fractions, we need a common denominator:

13/8 - 5/4 = 13/8 - 10/8 = 3/8

Now the expression becomes:

3/8 - 0.475

To subtract the decimal from the fraction, we need to convert the fraction to a decimal:

3/8 = 0.375

So the expression becomes:

0.375 - 0.475 = -0.1

Therefore, ((13/8 - 15/12) - 0.475) is equal to -0.1.
