Daniela bought a large package of potato chips
On the first day, she ate of the package
On the second day, she ate of the package
On the third day, how much does she have left to eat?
To solve this problem, we'll proceed with the following steps:
Step 1: Addition of Fractions
Combine the fractions of chips eaten on both days:
Find a common denominator for the fractions. The least common multiple of 6 and 8 is 24. Convert each fraction:
Add the converted fractions:
This means Daniela ate of the package.
Step 2: Subtract from the whole
The whole package is represented by 1. To find out how much is left, subtract what she ate from 1:
Therefore, the solution to the problem is that Daniela has of the package left to eat.
Solve the following exercise:
\( \frac{3}{9}+\frac{1}{9}=\text{?} \)
List the multiples of each number: 6: 6, 12, 18, 24... and 8: 8, 16, 24... The smallest common multiple is 24, so that's your LCD!
You need to find the total amount eaten first! If you subtract separately, you'd get negative amounts. Always add what was consumed, then subtract from the whole.
Check your work! If someone ate more than the whole package, something went wrong. The remaining amount must be less than 1 (and positive).
Yes, but be careful with rounding errors! and . Fractions give exact answers.
Check if 1 and 24 share any common factors. Since 1 only has itself as a factor, is already in simplest form!
