6:7
They are: 10 to 14 and 15 to 21
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
21 : 7 = 42 : 14
There are many. Two simplest ones are: 10:14 15:21

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.
Ah, ratios are like little fractions that compare two numbers. So, the ratio of 6 over 7 simply means you have 6 parts out of a total of 7 parts. It's like saying you have 6 happy little trees out of 7 in your forest painting. Just remember, ratios are all about comparing quantities and seeing how they relate to each other.
21 : 7 = 42 : 14
There are many. Two simplest ones are: 10:14 15:21
Each number can be reduced by two, and no more. So 7:6.
It is 7/6.
They are: 20 to 14 and 30 to 21
