Answer 1

(1 3/5+1,8)*1/2=(1,6+1,8)*0,5=3,4*0,5=1,7

Answer 2

(13/5+1.8)*1/2=(2.6+1.8)*1/2=4.4*0.5=4.9

Answer 3

To solve this expression, we'll first need to convert the mixed number 1 3/5 to an improper fraction.

1 3/5 = 8/5

So the expression becomes:

(8/5 + 1.8) * 1/2

Next, we can add the fractions and decimals together, and simplify the expression:

(8/5 + 9/5) * 1/2 = 17/5 * 1/2 = 17/10

Therefore, the result of the expression (1 3/5 + 1.8) * 1/2 is 1.7 or 17/10.
