There are many. Two simplest ones are: 10:14 15:21
They are: 10 to 14 and 15 to 21
21 : 7 = 42 : 14
You can produce an infinite number of ratios that are equal 3:7. You can do this by simply multiplying both 3 and 7 by the same number, so for example: 3 x 2:7 x 2 6:14 = 3:7 3 x 5:7 x 5 15:35 = 3:7

If we are talking ratios, then no. 14 to 10 is the same as 14/10 or 7/2. 7/2 is 3.5.
7/10
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.
21 : 7 = 42 : 14
10/7 ÷ 2 = 5/7
