Chapter 4: Problem 93
A special on a cruise to the Bahamas is advertised to be \(\frac{2}{3}\) of the regular price. If the regular price is \(\$ 2757,\) what is the sale price?
Short Answer
Expert verified
The sale price of the cruise is $1838.
Step by step solution
01
Understand the Problem
The problem asks us to find the sale price of the cruise, which is advertised as \(\frac{2}{3}\) of the regular price. We know the regular price is \\(2757. Our task is to calculate what \(\frac{2}{3}\) of \\)2757 is.
02
Write the Expression
To find the sale price, we need to multiply the regular price by \(\frac{2}{3}\). This can be written as the expression: \( \text{Sale Price} = \frac{2}{3} \times 2757 \).
03
Perform the Calculation
Calculate \(\frac{2}{3} \times 2757\). First, multiply 2757 by 2, which gives you 5514. Then, divide 5514 by 3 to find \(\frac{2}{3}\) of 2757.
04
Simplify and Find the Sale Price
Divide 5514 to find the sale price: \(5514 \div 3 = 1838\). Thus, the sale price of the cruise is \$1838.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Multiplication of Fractions
Multiplying fractions is a crucial skill in mathematics, especially when calculating values like discounts or parts of a whole. The primary rule to remember is that multiplication of fractions involves multiplying the numerators together, and then multiplying the denominators together. However, things are slightly different when you multiply a whole number by a fraction.
For instance, in our problem, we are tasked to find \( \frac{2}{3} \) of the regular price. This requires multiplying the regular price \( 2757 \) by \( \frac{2}{3} \). Effectively, you approach this by multiplying the whole number by the numerator:
For instance, in our problem, we are tasked to find \( \frac{2}{3} \) of the regular price. This requires multiplying the regular price \( 2757 \) by \( \frac{2}{3} \). Effectively, you approach this by multiplying the whole number by the numerator:
- First, multiply the whole number (2757) by the numerator (2): \( 2757 \times 2 = 5514 \).
- Next, divide the result by the denominator (3): \( 5514 \div 3 \).
Division in Arithmetic
Division is often used in practical scenarios to split a value into equal parts, and it's an essential arithmetic operation for many real-world applications. In this problem, we have used division to find a fraction of a whole number.
After multiplying by 2 to get \( 5514 \), the next crucial step is dividing by 3. Here, division helps in distributing that multiplied value into three equal parts. Calculating \( 5514 \div 3 \) gives us 1838, assisting us in determining what two-thirds of 2757 is.

The key steps for executing division of numbers include:
- Identifying how many times the divisor fits into parts of the dividend progressively.
- Multiplying the divisor with the current quotient part.
- Subtracting to carry the remainder to the next part of the dividend.
