1 Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator. 1.6 to 4

To convert the ratio 1.6 to 4 into a fraction, first recognize that both numbers can be multiplied by 10 to eliminate the decimal, resulting in 16 to 40. Now, we express it as a fraction: \( \frac{16}{40} \). To simplify, we can divide both the numerator and the denominator by their greatest common divisor, which is 8: \( \frac{16 \div 8}{40 \div 8} = \frac{2}{5} \). So, the simplest form is \( \frac{2}{5} \). If you're unsure about simplifying fractions, a common mistake is assuming you can't reduce them when they can. Always check for the greatest common factor, and remember that even large numbers can often be simplified down to smaller numbers. Practice with a few examples, and you’ll be a fraction pro in no time!
