Step 1
Solve the following proportions,

\frac{n}{12} = \frac{6}{18}

Cross-multiply the given equation,we get

18 \times n = 6 \times 12

Dividing both sides by 18, we get

\frac{18 \times n}{18} = \frac{6 \times 12}{18}

n = 4

is the solution.
Step 2
Solve the following proportions,

(\frac{3.5}{7.2}) = (\frac{k}{57.6})

Cross-multiply the given equation,we get

3.5 \times 57.6 = k \times 7.2

Dividing both sides by 7.2, we get

\frac{3.5 \times 57.6}{7.2} = \frac{k \times 7.2}{7.2}

k = 28

is the solution.
Step 3
Simplify the following ratio 50 to 40

= \frac{50}{40} = \frac{5}{4}

Solution

= 5

to 4.
Step 4
Simplify the following ratio 44 to 80

= \frac{44}{80} = \frac{11}{20}

Solution

= 11

to 20.
