What number is 75% of 4?   (or   Find 75% of 4.)
 
The PERCENT always goes over 100.
    (It's a part of the whole 100%.)
 

4 appears with the word of:
    It's the WHOLE and goes on the bottom.
 


 
We're trying to find the missing PART (on the top).
 
In a proportion the cross-products are equal:   So 4 times 75 is equal to 100 times the PART.
 
The missing PART equals 4 times 75 divided by 100.
 
(Multiply the two opposite corners with numbers; then divide by the other number.)
 

 
4 times 75 = 100 times the part
 
300 = 100 times the part
 
300/100 = 100/100 times the part
 
3 =   the part
