Oct 13, 2025 by wbrum.org 54 views

Introduction

Jasper, a sports enthusiast, had a sports card album that held 100 cards. He was meticulous about filling his album with his favorite football and baseball cards. However, after carefully examining his album, he realized that he had filled only a portion of it. In this article, we will delve into the world of fractions and help Jasper determine the fraction of the album that is still empty.

The Football Cards

Jasper filled $\frac{42}{100}$ of the album with football cards. To understand the significance of this fraction, let's break it down. The denominator, 100, represents the total number of cards in the album, which is 100. The numerator, 42, represents the number of football cards that Jasper had filled in the album.

Football cards filled: 42/100

The Baseball Cards

Jasper's baseball cards filled $\frac{3}{10}$ of the album. To compare this fraction with the football cards, we need to find a common denominator. The least common multiple of 100 and 10 is 100. Therefore, we can rewrite the fraction as $\frac{30}{100}$ .

Baseball cards filled: 30/100

Calculating the Fraction of the Album Filled

To find the fraction of the album filled with football and baseball cards, we need to add the two fractions. Since the denominators are the same, we can simply add the numerators.

Fraction of the album filled = (42 + 30)/100
= 72/100

Calculating the Fraction of the Album Still Empty

To find the fraction of the album still empty, we need to subtract the fraction of the album filled from 1. Since the fraction of the album filled is $\frac{72}{100}$ , we can subtract it from 1 as follows:

Fraction of the album still empty = 1 - 72/100
= (100 - 72)/100
= 28/100

Conclusion

In conclusion, Jasper filled $\frac{72}{100}$ of his sports card album with football and baseball cards. Therefore, the fraction of the album still empty is $\frac{28}{100}$ . This means that Jasper has 28 cards left to fill in his album.

Final Answer

The fraction of the album still empty is $\boxed{\frac{28}{100}}$ .

Additional Tips and Tricks

When adding fractions with different denominators, find the least common multiple of the denominators and rewrite the fractions with the common denominator.
When subtracting fractions, subtract the numerators and keep the common denominator.
To find the fraction of a quantity that is still empty, subtract the fraction of the quantity that is filled from 1.

Real-World Applications

In real-world scenarios, fractions are used to represent parts of a whole. For example, a pizza that is cut into 8 slices can be represented as $\frac{1}{8}$ of a pizza.
Fractions are also used in cooking and baking to measure ingredients. For example, a recipe may call for $\frac{1}{2}$ cup of sugar.
In finance, fractions are used to represent interest rates and investment returns. For example, a 5% interest rate can be represented as $\frac{5}{100}$ .

Common Misconceptions

Many people believe that fractions are only used in mathematics. However, fractions are used in various real-world applications, such as cooking, finance, and science.
Some people may think that fractions are difficult to understand. However, with practice and patience, anyone can master fractions and use them to solve problems.
