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.
Answer:
720 pennies
Step-by-step explanation:
The difference between the fraction originally contained in the bank (1/2) and the fraction that remains after Maria removes 120 pennies (1/3) represents the fraction occupied by the 120 pennies.
Therefore the fraction occupied by the 120 pennies= 1/2-1/3=1/6
thus if 1/6 of the bank can hold 120 pennies, then, when full it holds 120×6/1=720 pennies
