Ratios, Proportions, and Percents Tuesday's scribe

Percent, just like fractions, describe how many parts out of a whole. In percent, the part is compared to 100.
A percent is a ratio that compares a number to 100

Example:

1/4=25/100=25%=.25

5/11=.45=45%

Of in mathematics mean multiply.
Is in mathematics mean equal.

Example:

276/x=60/100

276•100/60=60x/60

x=460

Regina is the scribe for Wednesday's class.
