Question from Ashleigh, a student: Hi, I am dealing with ratios of me and 9 other students. I was wondering how you turn an arm span and height into a ratio? for example if a person has a height of 62 and an arm span of 63 what would the ratio be for that? |
Hi Ashley,
You could say the ratio of her height to her arm span is 62:63. You could convey the same information as a fraction by saying that her height is 62/63 of her arm span. Since 62/63 = 0.98 you could also say that her height is 98% of her arm span.
You might also turn this around and say that the ratio of her arm span to her height is 63:62.
I hope this helps,
Penny
