Two equivalent ratios for 2 to 7 are 4 to 14 and 6 to 21. These ratios maintain the same proportion as the original ratio by multiplying both the numerator and denominator by the same factor (2 and 3, respectively).
7 to 2 and 21 to 3
Two equivalent ratios for ( \frac{15}{7} ) can be found by multiplying both the numerator and the denominator by the same number. For example, multiplying by 2 gives ( \frac{30}{14} ), and multiplying by 3 gives ( \frac{45}{21} ). Therefore, ( \frac{30}{14} ) and ( \frac{45}{21} ) are both equivalent ratios to ( \frac{15}{7} ).
Three equivalent ratios of 14 to 2 are 28 to 4, 42 to 6, and 56 to 8. These ratios maintain the same relationship between the two numbers, as each pair can be simplified back to 7 to 1, which is the simplest form of the original ratio.
7/15 = 14/30 = 70/150
7 to 2, 28 to 8 and 56 to 16

50 to 70 and 55 to 77 are two examples.
1:2 and 1:7, possibly.
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.
7/15 = 14/30 = 70/150
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.
7 to 2, 28 to 8 and 56 to 16
