1) 3.4 / 5 *100
2) let x% of 930 = 720
then x/100*930 = 720
solve to get the value of x
3)let 15 is x% of 120
then x/100*120 = 15
Solve to get x
Rest do yourself
All the best

well heres the formula:
90/100=90%
90 is the part
100 is the base
90% is the rate
there are 3 types of problems:
Rate & Base= part...... rate X base = part
(remember to convert rate to decimal)
Base & part = rate......Base/part (base devided by part) = rate, change to percent
Rate & part = base......part/base (part devided by rate) = base
(remember to convert rate to decimal)
if you have any other questions, email me.
