If we are talking ratios, then no. 14 to 10 is the same as 14/10 or 7/2. 7/2 is 3.5.
1/2 is equivalent to 7/14. Ratios are just like fractions, so this is how you know: If you take 1/2 and multiply both the top and bottom by 7, you will get 7/14. As long as you multiply both the top and bottom by the same number, you will get equivalent fractions.
Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. Next, multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14, and multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7. Students are also asked to determine whether two given ratios are equal, by first writing each ratio as a fraction, then writing each fraction in lowest terms. If the two fractions are the same when written in lowest terms, then the ratios are equal.
5:7 (or 5/7) is equivalent to 10:14 (10/14) and 15:21 (15/21).
