Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Perform the multiplication first: -5/18 × 0.9
2. Perform the division next: 1/9 ÷ 0.5
3. Finally, add the results of the multiplication and division.

Let's solve it step by step:

1. -5/18 × 0.9 = -0.05

2. 1/9 ÷ 0.5 = 1/9 × 2 = 2/9

Now, add the results:

-0.05 + 2/9

To add these two fractions, we need to find a common denominator. The common denominator of 9 and 100 is 900 (LCM).

-0.05 = -5/100 2/9 = 200/900

Now, add the fractions:

-5/100 + 200/900 = -5/100 + 200/900 = (200 - 5) / 900 = 195/900

To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor (GCD):

GCD(195, 900) = 15

195/900 ÷ 15/15 = 13/60

So, the final result is 13/60.
