Answer:
1080
Step-by-step explanation:
We take x to be the number of pennies in the bank at first which filled the bank by a ¹/3
¹/3=×
⁷/9=×+480
⅓ multiply by 3 with both the numerator and denominator to get 3/9
7/9-3/9=4/9
4/9=480
If 4/9=480 what of 9/9
9/9×480÷4/9
Reciprocate 4/9
9/9×480×9/4=1080
