Answer:
300
Step-by-step explanation:
Since 225 is 75% of a whole, write the proportion such that 225 corresponds to 75% and x, the number we're searching for, corresponds with 100%
Cross multiply to solve and divide by 75 to isolate x:
225 x 100 = 75x
22500 = 75x
300 = x
25% of 700 is 175.
So the answer would be 175.
The result is always divisible by 3.
