Fraction Subtraction Problem: Finding Remaining Amount After 5/6 and 1/8 Consumption

Question

Daniela bought a large package of potato chips

On the first day, she ate 56 \frac{5}{6} of the package

On the second day, she ate 18 \frac{1}{8} of the package

On the third day, how much does she have left to eat?

Video Solution

Solution Steps

00:00 Found the remaining part in the bag
00:04 We want to find the total eaten part and subtract it from the whole
00:07 We'll combine the eaten parts according to the given data
00:10 We want to find the smallest common denominator
00:14 We'll multiply the fractions by 3 and 4 respectively to find the common denominator
00:17 Remember to multiply both numerator and denominator
00:26 Let's calculate the multiplications
00:39 We'll add under the common denominator
00:42 Let's calculate the numerator
00:45 This is the part that was eaten from the bag
00:56 Now we'll subtract this part from the whole to find the remaining part
01:06 We'll convert whole to fraction
01:16 We'll add under the common denominator
01:20 Let's calculate the numerator
01:26 And this is the solution to the problem

Step-by-Step Solution

To solve this problem, we'll proceed with the following steps:

  • Step 1: Calculate the total amount of potato chips eaten over two days.
  • Step 2: Subtract the eaten amount from the whole (1) to find what's left.

Step 1: Addition of Fractions
Combine the fractions of chips eaten on both days:

56+18 \frac{5}{6} + \frac{1}{8}

Find a common denominator for the fractions. The least common multiple of 6 and 8 is 24. Convert each fraction:

56=5×46×4=2024 \frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24}

18=1×38×3=324 \frac{1}{8} = \frac{1 \times 3}{8 \times 3} = \frac{3}{24}

Add the converted fractions:

2024+324=20+324=2324 \frac{20}{24} + \frac{3}{24} = \frac{20 + 3}{24} = \frac{23}{24}

This means Daniela ate 2324 \frac{23}{24} 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:

12324=24242324=124 1 - \frac{23}{24} = \frac{24}{24} - \frac{23}{24} = \frac{1}{24}

Therefore, the solution to the problem is that Daniela has 124 \frac{1}{24} of the package left to eat.

Answer

124 \frac{1}{24}
