What number is 80% of 90?

OpenStudy (danjs):

\[\frac{ 80 }{ 100 }*90 = x\]

OpenStudy (agl202):

72% I belive

OpenStudy (danjs):

72

OpenStudy (anonymous):

yes, it is 72 :)

OpenStudy (agl202):

Multiply 80 by 100 then times by 90

OpenStudy (danjs):

7200 / 100 = 72

OpenStudy (agl202):

yep!!!

OpenStudy (danjs):

no agl202 is incorrect

OpenStudy (danjs):

follow the original expression i wrote at the top

OpenStudy (anonymous):

An easier way would be just .8 x 90, and .8 is gotten by doing 80/100. Answer ends up being 70%

OpenStudy (danjs):

The answer is not 70%, it is the number 70
