Wondering how to figure out which fraction is bigger without a calculator? Comparing \(\frac{4}{7}\) and \(\frac{1}{10}\) is straightforward once you know the right approach. Below we walk through three proven methods for comparing fractions: finding a common denominator, cross multiplication, and converting to decimals. Each method will give you the same answer, so choose the one that feels easiest.
To compare these fractions, we need a common denominator. The denominators are 7 and 10, and the least common denominator (LCD) is 70.
A quicker way to compare fractions is to cross-multiply. Multiply each numerator by the other fraction's denominator:
Convert each fraction to a decimal by dividing the numerator by the denominator:
Since 0.571429 is greater than 0.1, we confirm that \(\frac{4}{7} > \frac{1}{10}\). In percentage terms, \(\frac{4}{7}\) is 57.1429% and \(\frac{1}{10}\) is 10%, a difference of 47.1429 percentage points.
These fractions have different numerators and different denominators, so we can't compare them directly. By converting to a common denominator of 70, we're cutting both quantities into equal-sized pieces. Then 40 pieces vs 7 pieces is a straightforward comparison.
\(\frac{4}{7}\) is bigger. As a decimal, \(\frac{4}{7}\) = 0.571429 while \(\frac{1}{10}\) = 0.1.
The difference is \(\frac{33}{70}\), which equals 0.471429 in decimal form (47.1429 percentage points).
You can use three methods: find a common denominator and compare numerators, cross-multiply and compare the products, or convert both fractions to decimals. All three methods confirm that \(\frac{4}{7}\) \(>\) \(\frac{1}{10}\).
