Reducing to lowest terms simply means dividing both the numerator and the denominator by the same amount so as to get an equivalent fraction that has lower numbers so it looks nicer.
For example, we know that 1/4 = 2/8 = 4/16 = 10/40.
So for 18/32, let's start by diving both numbers by 2, to give 9/16. 9 and 16 can't be divided by the same number so 18/32 in it's lowest terms is 9/16.
By lowest terms, it simply means to it's simplest form. To do that, you have to find a number that can divide the two numbers involved. That number is 2. When 2 divides 18, you get 9. When 2 divides 32, you get 16. So you get; 9/16. And that is the final answer because nothing else can divide the two numbers. To make you understand better, i am using a different fraction. So; 16/8 Once again, 2 can divide. But you can also use 8. If you use 2, it will be 8/4, 2 can still divide, so that will be 4/2. 2 divides again, making it 2/1, which is the same as 2. If you use 8, it will be 2/1. Which is still 2. So as you can see, no matter the number used, the answer remains the same. Hope i helped. Have a nice day.
