Question

15,25-4 1/6-(5,15-2 2/3)=

Answer 1

1) 5,15-2 2/3=515/100-8/3=101/20-8/3=303/60-160/60=143/60=2 23/60
2) 15,25-4 1/6=1525/100-25/6= 61/4-25/6=183/12-50/12=133/12=11 1/12
3) 11 1/12-2 23/60=133/12- 143/60=665/60-143/60=522/60=174/20=87/10=8,7

Answer 2

15,25-4 1/6-(5,15-2 2/3)=10,6

Answer 3

Let's break down the expression step by step:

1. 15,25 - 4 = 11,25
2. 1/6 - 2 2/3 = -2 2/3 + 1/6 = -2 4/6 + 1/6 = -2 5/6

Now, we can substitute these values back into the original expression:

11,25 - (-2 5/6)

To subtract a negative number, we can add the positive of that number:

11,25 + 2 5/6

Now, let's add the whole numbers and fractions separately:

Whole numbers: 11 + 2 = 13 Fractions: 25/100 + 5/6 = (25/100) * (3/3) + 5/6 = 75/300 + 5/6 = 75/300 + 50/300 = 125/300

Now, we have:

13 + 125/300

To simplify further, we can find a common denominator:

13 + 125/300 = 13 + 5/12

Now, add the whole number and the fraction:

13 + 5/12 = 13 5/12

So, the final result is 13 5/12.
