Question:

One morning, Mirna counted 15 junk emails out of 21 e-mails in her inbox. How do you write a ratio comparing the number of regular e-mails to the junk emails?

Answers

#2:5#
So, for every 2 regular emails, there are 5 junk emails.

Explanation:

A ratio is a comparison between two quantities with the same unit.
It does not say many items there are altogether, only how many of one for how many of the other.

Ratio's are written
- in simplest form
- no fractions and no decimals
-no units (but the units are the same before being discarded)

She has 21 emails altogether - some junk and some regular
If there are 15 junk emails, there must be 6 regular emails

NOte: The order of how the numbers are written is important:

regular emails : junk emails

#color(white)(xxxxxxxx)6 : 15 " "larr div 3#
#color(white)(xxxxxxxx)2 : 5#

So, for every 2 regular emails, there are 5 junk emails.
