Introduction Decimals and fractions are two ways of expressing parts of a whole. Converting a decimal to a fraction involves expressing the decimal as a ratio of two integers. The decimal 1.75, which signifies one and seventy-five hundredths, can be written as the fraction 7/4. This conversion is straightforward once you understand the place value of the digits after the decimal point. By following a few simple steps, you can transform any terminating decimal into a fraction in its simplest form. This article will break down the conversion process for 1.75, explore why this fraction is equivalent, and answer frequently asked questions about this specific conversion.

Steps to Convert 1.75 to a Fraction

1. Write the Decimal as a Fraction Over 1: Start by expressing the decimal as a fraction where the decimal itself is the numerator and 1 is the denominator. For 1.75, this gives us 1.75/1.
2. Eliminate the Decimal Point: To remove the decimal, multiply both the numerator and the denominator by 10 for each digit after the decimal point. Since 1.75 has two digits after the decimal (7 and 5), multiply both numerator and denominator by 100 (10 * 10).
   • Numerator: 1.75 * 100 = 175
   • Denominator: 1 * 100 = 100
   • This gives us the fraction 175/100.
3. Simplify the Fraction: The fraction 175/100 is not in its simplest form. To simplify, find the greatest common divisor (GCD) of the numerator (175) and the denominator (100). The GCD of 175 and 100 is 25.
   • Divide both the numerator and the denominator by 25:
     • 175 ÷ 25 = 7
     • 100 ÷ 25 = 4
   • The simplified fraction is 7/4.

Conclusion That's why, the decimal 1.75 is exactly equivalent to the fraction 7/4. This can also be expressed as a mixed number: 1 and 3/4. The process of converting decimals to fractions relies on understanding place value and simplifying the resulting fraction to its lowest terms. This skill is essential for solving problems in mathematics, science, engineering, and daily life.

Scientific Explanation The conversion process leverages the base-10 place value system. The digit '7' in 1.75 is in the tenths place, and the digit '5' is in the hundredths place. Writing 1.75 as 175/100 explicitly shows that it represents 175 hundredths. Simplifying this fraction by dividing both parts by their GCD (25) reduces it to 7/4, which represents 7 fourths. This demonstrates that 1.75 is precisely 1 whole (4/4) plus 3/4, totaling 7/4. The fraction 7/4 is in its simplest form because 7 and 4 share no common factors other than 1 Not complicated — just consistent. Took long enough..

FAQ

• Why do we simplify fractions? Simplifying fractions makes them easier to understand, compare, and use in calculations. It expresses the ratio in its most reduced form, avoiding unnecessary large numbers.
• Can 1.75 be written as a mixed number? Yes, 1.75 is equivalent to the mixed number 1 3/4. This is found by dividing 7 by 4, which gives a quotient of 1 and a remainder of 3, so 1 whole and 3/4.
• Is 1.75 exactly 7/4? Yes, 1.75 is exactly equal to 7/4. This is a precise mathematical equivalence.
• How do I convert other decimals to fractions? The process is similar: write the decimal over 1, multiply numerator and denominator by 10 for each decimal place, then simplify by dividing both by their GCD. Take this: 0.625 becomes 625/1000, then simplifies to 5/8.

Continuing the discussion on decimal-to-fraction conversion, it's crucial to recognize that this foundational skill extends far beyond simple arithmetic exercises. A decimal like 3.g.That's why for instance, in engineering, precise measurements often require converting decimal readings from instruments into fractional equivalents for calculations involving tolerances, material dimensions, or structural load calculations. 75 inches might need to be expressed as 15/4 inches for compatibility with specific blueprint specifications or manufacturing processes. , 4.The ability to translate between these two representations of rational numbers is indispensable in numerous practical domains.

Worth adding, this conversion process inherently reinforces a deep understanding of the base-10 place value system. The decimal point acts as a separator, defining the magnitude of each digit's contribution. 75 to 175/100 explicitly visualizes this: the '7' in the tenths place becomes 70 hundredths, and the '5' in the hundredths place is 5 hundredths, collectively forming 75 hundredths, which is 175 hundredths when combined with the whole number part (100 hundredths). This explicit representation highlights how the decimal system efficiently compresses large place values into a compact notation. Plus, converting 1.
