2 What is 0.7 written as a fraction? (A) \( \frac{1}{100} \) (B) \( \frac{1}{7} \) (C) \( \frac{7}{100} \) (D) \( \frac{7}{10} \)

To express 0.7 as a fraction, think of it as 7 tenths. So, you can write it as \( \frac{7}{10} \). This means you have 7 parts out of a total of 10. The correct answer is (D) \( \frac{7}{10} \). Now, let’s spice things up a bit! Did you know that fractions have been used since ancient times? The Egyptians had a unique way of expressing fractions, especially using unit fractions—those with 1 in the numerator. It’s fascinating how such mathematical concepts have evolved over thousands of years! And here’s a pro tip: if you ever find yourself unsure about converting decimals to fractions, remember this simple trick: take the decimal, count the number of digits to the right of the decimal point, and use that as your denominator (for 0.7, that’s 10, since there is one digit). Always simplify if possible!
