Answer:

$\frac{17}{18}$

Step-by-step explanation:

To solve 4/9 + 9/18 just find the common denominator which is 18.

to get 4/9 to get the denominator of 18 you multiply the denominator by 2:

9 x 2 = 18, what you do to the bottom you do to the top (Multiply the numerator by 2 also) so, 4 x 2 = 8.

Now, add the numerator and keep the denominator the same. 8 + 9 = 17.

8/18 + 9/18 = 17/18

Answer:

$\boxed{0.2}$

Step-by-step explanation:

Convert $\dfrac{12}{60}$ to a decimal

Step 1. Reduce the fraction to its lowest terms.

Divide both numerator and denominator by their greatest common factor (12)

$\dfrac{12}{60} =\dfrac{1}{5}$

Step 2. Convert the denominator to a power of 10

Multiply both numerator and denominator by 2.

$\dfrac{1}{5} \times \dfrac{2}{2} = \dfrac{2}{10}$

Step 3. Divide the numerator by the denominator

Dividing by 10 moves the decimal point one place to the left.

$\dfrac{2}{10} = \boxed{0.2}$
