Gil's Birthday Cake: A Math Problem
Gil's birthday cake was cut into 32 equal pieces, and 18 of them were eaten at the party. The remaining pieces of cake are a fraction of the total cake. In this article, we will calculate the fraction of the cake that was left.
To solve this problem, we need to understand the concept of fractions and how to calculate them. A fraction is a way to represent a part of a whole. It consists of a numerator (the number on top) and a denominator (the number on the bottom). The numerator tells us how many equal parts we have, and the denominator tells us how many equal parts the whole is divided into.
Let's start by identifying the information given in the problem:
- The cake was cut into 32 equal pieces.
- 18 pieces were eaten at the party.
To find the fraction of the cake that was left, we need to subtract the number of pieces eaten from the total number of pieces.
Step 1: Subtract the Number of Pieces Eaten from the Total Number of Pieces
total_pieces = 32
pieces_eaten = 18
pieces_left = total_pieces - pieces_eaten
Step 2: Calculate the Fraction of Cake Left
Now that we know the number of pieces left, we can calculate the fraction of the cake that was left. To do this, we need to divide the number of pieces left by the total number of pieces.
fraction_left = pieces_left / total_pieces
The fraction we calculated may not be in its simplest form. To simplify the fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator and divide both numbers by the GCD.
Step 1: Find the GCD of the Numerator and the Denominator
import math
gcd = math.gcd(pieces_left, total_pieces)
Step 2: Simplify the Fraction
Now that we know the GCD, we can simplify the fraction by dividing both the numerator and the denominator by the GCD.
simplified_fraction = (pieces_left // gcd) / (total_pieces // gcd)
In conclusion, we calculated the fraction of the cake that was left by subtracting the number of pieces eaten from the total number of pieces and then simplifying the resulting fraction. The fraction of the cake that was left is .
The correct answer is A. .
This problem is a great example of how math can be applied to real-life situations. It requires the student to understand the concept of fractions and how to calculate them. The student must also be able to simplify the fraction to its simplest form.
- Make sure to read the problem carefully and understand what is being asked.
- Use a calculator or a computer program to help with the calculations.
- Simplify the fraction to its simplest form to make it easier to understand.
- If 24 pieces of cake were eaten at the party, what fraction of the cake was left?
- If the cake was cut into 40 equal pieces, and 20 pieces were eaten at the party, what fraction of the cake was left?
