hint \[5 \text % \; \text{of}\; 120 \implies 0.05 \times 120\]

OpenStudy (lgbasallote):
divide 60 by 100 then multiply to 1000
OpenStudy (lgbasallote):
\[\implies \frac{60}{100} \times 1000\]

idk i guessed
OpenStudy (lgbasallote):
to turn percent into fraction divide by 100. for example
70% of 700 is \[\frac{70}{100} \times 700\]
so what is 50% of 700 then?
OpenStudy (anonymous):
490
OpenStudy (lgbasallote):
that is 70% of 700......
OpenStudy (lgbasallote):
if 70% is \[\frac{70}{100}\] then what is 50%?
