Answer:
1 : 30
Step-by-step explanation:
4 seconds : 2 min
however we know that 1 min has 60 seconds. Hence 2 min will have 2 x 60 = 120 seconds
Therefore we can substitute 2 min with 120 seconds
4 seconds : 2 min
4 seconds : 120 seconds (simplify by dividing both sides by 4)
4/4 : 120/4
1 : 30
A ratio is simply the relationship has with another quantity. Most of the times ratios are written in the form A : B. Notice the colon in the middle? Another way, and often confusing to students new to ratios, is write them just like you would with a fraction: [tex]\frac{A}{B}[/tex]
In this case we have four seconds to 2 minutes. We can write down both ways and shown earlier.
Typical ratio format: 4 seconds : 2 minutes
Fraction like: [tex]\frac{4 seconds}{2 minutes}[/tex]
