Question

45 : 3 6/13 - 13,6 + 1 3/8=?

Answer 1

45:3 6/13-13.6+1 3\8=
1)45:45/13=45*13/45=13
2)13-13,6=-0.6
3) -0.6+1 3\8=-0.6+11/8=1,375-0.6=0,775

Answer 2

To solve the expression 45 : 3 6/13 - 13.6 + 1 3/8, we need to follow the order of operations (PEMDAS/BODMAS) to simplify it step by step.

First, let's convert all the mixed numbers into improper fractions:

45 : 3 6/13 - 13.6 + 1 3/8 = 45 : (3 + 6/13) - 13.6 + (1 + 3/8) = 45 : (39/13 + 6/13) - 13.6 + (1 + 3/8) = 45 : (45/13) - 13.6 + (8/8 + 3/8) = 45 : (45/13) - 13.6 + (11/8)

Next, let's perform the division:

45 : (45/13) can be rewritten as 45 × (13/45) = (45 × 13) / 45 = 585 / 45

Substituting this into the expression, we have:

(585/45) - 13.6 + (11/8)

Now, let's simplify further by finding a common denominator for the fractions:

(585/45) - 13.6 + (11/8) = (585/45) - (13.6 * (45/45)) + (11/8) = (585/45) - (612/45) + (11/8)

Now that we have a common denominator, we can combine the fractions:

= (585 - 612 + (11 * 5)) / 45 = (585 - 612 + 55) / 45 = (28 + 55) / 45 = 83/45

Therefore, the value of the expression 45 : 3 6/13 - 13.6 + 1 3/8 is 83/45.
