Let p = number of pennies we need to find.

(3/10)/(4/5) = p/440

Solve for p to find your answer.

Answer:

880

Step-by-step explanation:

Multiply the numerator and the denominator of 4/5 by 2 so it can be added. Rachel's bank would now be 8/10 full. If 440 pennies made it half full (8/10-3/10= 5/10, which equals 1/2) then 880 pennies (440 times 2) would fill it up completely. Hope this helps!
