Write each statement as a proportion using colons. A. 4 is to 20 as 2 is to 10. B. 9 is to 27 as 2 is to 6.
Question
Answer:
RemarkYou should always write proportions the way you normally do first. Most people write a proportion as
4/20 = 2 / 10 Using colons helps to make clear what is comparred all on one line.
4:20::2:10
:: is the equal sign
/ is the division sign.
: (a single colon) takes the place of /
9/27 = 2 / 6
Which can be
9:27::2:6
Note
The colon method is not in current use as much as it was.
