explain the following ratios in their simplest form (1) 120m to 2km (2) $4.32 to $1.80 pls show working

1) 120 m : 2 km

Ratio is always between the same quantities so either we'll convert m to km or km to m

It is better to convert km to m

=> For converting km to m, we'll multiply by 1000

=> 120 m : 2000 m

Dividing by 40

=> 30 m : 500

Now 10

=> 3 m : 50 m

2) $4.32 : $1.80

Multiplying by 100

=> $432 : $180

Dividing by 6

=> $72 : $30

Dividing by 6

=> $12 : $5        

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
