Answer:
1 : 3.2
Step-by-step explanation:
You want the ratio 15 : 48 written as 1 : n.
Equivalent ratio
The equivalent ratio can be found by dividing (and/or multiplying) both terms by the same number. For the purposes of seeing what the final value will be, it is convenient to do this in stages:
15 : 48
= 5 : 16 . . . . . . . divide by 3
= 10 : 32 . . . . . . multiply by 2 (facilitates the final division)
= 1 : 3.2 . . . . . . divide by 10

Additional comment
As we show here, it is sometimes convenient to perform division by 5 by doing the equivalent: multiply by 2 and divide by 10.
