anonymous · Answer

Ok in this question we will jhave too convert wither of the quantity into others specs for here I will convert minutes into seconds(just to make it length and easy):

$$\frac{ 45 \sec }{ 30 \min }= \frac{ 45 \sec }{30 * 60 } = \frac{ 3 }{ 2  * 60} =\frac{ 1 }{ 2 * 20 }= \frac{ 1 }{ 40}=1:40$$

first change min to sec
$$30 \times 60= 1800mins$$
now you can continue like this
$$\frac{ 45 }{ 1800 }$$
then simplify the fraction to get
$$\frac{ 1 }{ 40 }$$
= 1:40

here, we NEED to convert both time into seconds and only then take ratio. 

45/1800=....
