Answer:
1.46:1
Step-by-step explanation:
Start by setting this up as a proportion:
[tex]\dfrac{89}{61} =\dfrac{n}{1}[/tex]
We need to solve for [tex]n[/tex].
We can use cross-multiplication, a common way to solve proportions. To do so, we would multiply the diagonals and set them equal to each other, like so:
[tex]89*1=61*n[/tex]
Simplify:
[tex]89=61n[/tex]
Now, to solve for [tex]n[/tex], we have to divide both sides by [tex]61[/tex] in order to isolate the variable:
[tex]\dfrac{89}{61} =\dfrac{61n}{61}[/tex]
Simplify, and per the instructions, round the decimal to 2 decimal places:
[tex]1.46=n[/tex]
Now, we can put this in to the original requested ratio, [tex]n:1[/tex]:
[tex]1.46:1[/tex]
