That's the same thing as saying 2/3 multiplied by 7/6.
So, the answer is 7/9.
The answer to the question is right
Answer:
35 one-dollar bills
18 ten dollar bills
Step-by-step explanation:
We can solve this problem by using logic. First we have to understand that if all the 53 bill were $10 bills, then the combined monetary value would be...
53 x $10 = 530$
Now we start to replace the $10 bills with 1$ and each time we replace 1 bill, the combined monetary value will decrease by...
$10 - $1 = $9
We also know that we need to decrease the combined monetary value all the way to $215, which mean there has to be...
(530 - 215) / 9 = 35 one dollar bills.
And now since we know there are 35 one-dollar bills, that means there has to be...
53 - 35 = 18 ten dollar bills
