Sure! Adding and subtracting fractions is a key skill that helps us solve everyday problems. Let’s look at how to do this with some easy examples.
Imagine you are baking a cake, and the recipe calls for (\frac{3}{4}) cup of sugar. If you’ve already added (\frac{1}{2}) cup of sugar, how much more do you need? Here’s how to figure it out step by step:
First, find a common denominator. In this case, the common denominator is 4.
Change (\frac{1}{2}) into (\frac{2}{4}).
Now, you can subtract:
[ \frac{3}{4} - \frac{2}{4} = \frac{1}{4} ]
So, you still need an extra (\frac{1}{4}) cup of sugar.
Let’s try another example. Say your friend has (\frac{5}{6}) of a pizza, and you eat (\frac{1}{3}) of it. Here’s how you can find out how much pizza is left:
First, change (\frac{1}{3}) to a fraction with a common denominator of 6. So, (\frac{1}{3} = \frac{2}{6}).
Then, you can subtract:
[ \frac{5}{6} - \frac{2}{6} = \frac{3}{6} = \frac{1}{2} ]
After eating, your friend has (\frac{1}{2}) of the pizza left.
These examples show us how adding and subtracting fractions can be really helpful in everyday life!
