marias penny bank is 1/2 full. after she removes 120 pennies, it is 1/3 full. how many pennies can marias bank hold​
liberstina [14]

Answer:

720 pennies

Step-by-step explanation:

Initially the Penny bank is 1/2 full

After removing 120 pennies it is 1/3 full;

Therefore. the fraction equivalent to 120 pennies is;

1/2 -1/3 = 1/6

Thus; Assuming the number of pennies that the penny bank can hold when full is x; then;

1/6 of x = 120

x = 120 × 6

   = 720 pennies

Hence, when the penny bank is full it can hold 720 pennies.
