What must #n# be if the ratio 6:7 is equivalent to 36:#n#?

Answer 1

#n# = 42

You first do #\frac {36} {6}# which equals 6. This is the constant that you are going to multiply by 7. Since you have to multiply by both sides on a ratio, you do 6#xx#6 and 6#xx#7. This equals 42. The final ratios are: 6:7 and 36:42

To find the value of ( n ), we set up a proportion:

[ \frac{6}{7} = \frac{36}{n} ]

Cross-multiplying, we get:

[ 6n = 7 \times 36 ]

[ 6n = 252 ]

[ n = \frac{252}{6} ]

[ n = 42 ]

So, ( n ) must be 42.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
