Understanding the Problem

To find the number that is one hundredth more than 4.53, we need to understand what "one hundredth" means. In decimal form, one hundredth is represented as 0.01. This means we need to add 0.01 to 4.53 to find the correct answer.

Calculating One Hundredth More than 4.53

To calculate one hundredth more than 4.53, we simply add 0.01 to 4.53.

4.53 + 0.01 = 4.54

Evaluating the Options

Now that we have calculated the correct answer, let's evaluate the options given:

A. 4.63 - This is not the correct answer, as it is 0.09 more than 4.53, not 0.01.

B. 4.54 - This is the correct answer, as it is 0.01 more than 4.53.

C. 5.54 - This is not the correct answer, as it is 1.01 more than 4.53, not 0.01.

D. 4.64 - This is not the correct answer, as it is 0.11 more than 4.53, not 0.01.

Conclusion

Based on our calculation, the correct answer is B. 4.54. This is the number that is one hundredth more than 4.53.

Why is Understanding Decimals Important?

Understanding decimals is crucial in mathematics, as it helps us perform calculations and make accurate measurements. In real-life scenarios, decimals are used in various applications, such as finance, science, and engineering. For example, in finance, decimals are used to calculate interest rates and investment returns. In science, decimals are used to measure the accuracy of experiments and measurements. In engineering, decimals are used to design and build structures and machines.

How to Calculate Decimals

In conclusion, understanding decimals is crucial in mathematics and has numerous real-life applications. By following the tips and techniques outlined in this article, you can become proficient in working with decimals and make accurate calculations.

Q: What is a decimal?

A: A decimal is a way of representing a number using a point (.) as the decimal separator. It is used to express fractions and numbers that have a fractional part.

Q: How do I read decimals?

A: To read decimals, you need to understand the place value of each digit. The digits to the left of the decimal point represent whole numbers, while the digits to the right of the decimal point represent fractions of a unit.

Q: How do I add decimals?

A: To add decimals, you need to line up the decimal points and add the numbers. For example, to add 4.53 and 0.01, you would line up the decimal points and add the numbers:

4.53

0.01

4.54

Q: How do I subtract decimals?

A: To subtract decimals, you need to line up the decimal points and subtract the numbers. For example, to subtract 0.01 from 4.53, you would line up the decimal points and subtract the numbers:

4.53

0.01

4.52

Q: How do I multiply decimals?

A: To multiply decimals, you need to multiply the numbers as if they were whole numbers, and then count the number of decimal places in the product. For example, to multiply 4.53 by 0.01, you would multiply the numbers as if they were whole numbers (453 x 1 = 453), and then count the number of decimal places in the product (2 decimal places).

Q: How do I divide decimals?

A: To divide decimals, you need to divide the numbers as if they were whole numbers, and then count the number of decimal places in the quotient. For example, to divide 4.53 by 0.01, you would divide the numbers as if they were whole numbers (453 ÷ 1 = 453), and then count the number of decimal places in the quotient (2 decimal places).

Q: What is the difference between a decimal and a fraction?

A: A decimal is a way of representing a number using a point (.) as the decimal separator, while a fraction is a way of representing a number as a ratio of two integers. For example, the decimal 0.5 is equivalent to the fraction 1/2.

Q: How do I convert a decimal to a fraction?

A: To convert a decimal to a fraction, you need to express the decimal as a ratio of two integers. For example, to convert the decimal 0.5 to a fraction, you would express it as 1/2.

Q: How do I convert a fraction to a decimal?

A: To convert a fraction to a decimal, you need to divide the numerator by the denominator. For example, to convert the fraction 1/2 to a decimal, you would divide 1 by 2 (1 ÷ 2 = 0.5).

Q: What is the importance of decimals in real-life applications?

A: Decimals are used in various real-life applications, including finance, science, engineering, cooking, and travel. They are used to calculate interest rates, measure the accuracy of experiments, design and build structures and machines, measure ingredients and cooking times, and calculate distances and travel times.

Q: How can I improve my understanding of decimals?

A: To improve your understanding of decimals, you can practice working with decimals, use online resources and calculators, and seek help from a teacher or tutor. You can also try to apply decimals to real-life situations to make them more meaningful and interesting.
