Final answer:
To rewrite the ratio 1:17 as n:1, we take the reciprocal of 17, which is about 0.06, so the ratio in the form n:1 is approximately 0.06:1. This process involves inverting the second term of the original ratio to establish its relationship to 1.
Step-by-step explanation:
To convert the ratio 1:17 to an equivalent form n:1, we need to find the value of n that would make the two ratios equal. To do this, we take the reciprocal of 17, which is 1 divided by 17. The decimal form of that is approximately 0.06. Therefore, the equivalent ratio in the form n:1 is approximately 0.06:1.
If we apply a similar approach to other ratios:
For the ratio 1/20 = 1/5.5, taking the reciprocal of 5.5 gives us approximately 0.18, so the equivalent ratio would be 0.18:1.
To rewrite the ratio 5/1 - 2.75/1 cm, we would subtract 2.75 from 5, leaving us with 2.25:1.
For the ratio 1/48=w/16, by cross-multiplying, we find that w equals 1/3 or approximately 0.33, making the ratio 0.33:1.
