$60 was spent
Total amount of money she had
= 60 + 30
= $90
Ratio of money she spent to total amount of money she had is 60:90, reduced to the simplest form is 2:3 (divide 60 and 90 by 30)

Sorry.....i dont understand its 60:90 so how is it 2:3 u sure correct
Because in ratio you have to simplify it to the simplest form, which means you cannot leave it as 60:90 since you can still divide them both by 30. 60 divided by 30 is 2, and 90 divided by 30 is 3, thus when you reduce 60:90 to it’s simplest form, it is 2:3.
So its correct for sure but i only learn the 2 to 9 times stable
Tjans
Zeroes can be cancelled at the end. Then it becomes 6 : 9, which simplifies to 2 : 3.
