Let’s start by finding out the number of withdrawals Elisa did!
She withdrew 20$ at a time for a total of 140$ at the end.
So you need to divide the final amount, which is 140$, by the amout that she withdrew each time, which is 20$ :
140 ÷ 20 = 7
Which means she withdrew 20$ 7 times in order to obtain a total of 140$!
⓶
Let’s see for Fracis now!
He withdrew 45$ at a time for a total of 270$ at the end.
So you need to divide the fin amount, which is 270$, by the amout that he withdrew each time, which is 45$ :
270 ÷ 45 = 6
Which means she withdrew 45$ 6 times in order to obtain a total of 270$!
⓷
If your question is “who made the greater number of withdrawals?”, then the answer would be Elisa, considering she withdrew money 7 times, which is one withdrawl over Fracis who withdrew money 6 times! ☻
