Question 24862
You translate them just as they are written;
the word "is" means equals,
the word "of" means multiply;
21 is what percent of 35? 
21=WP(35)
divide each side by 35;
{{{21/35}}}=WP
60%
what percent of 88 is 66? 
WP(88)=66
WP=75%
I believe the last twoyou have backward;
Find what percent of 12 is of 16. 
WP(16)=12
WP=75%
What percent of 300 is 450?
WP(450)=300
WP=66.7%
Hope you understand
=)
