No, 3819 is a number which is nearly 182 times as large as 21.
There are infinitely many equivalent ratios so it is not possible to list them all. They are elements of the set of ratios of the form 21*k : k where k is any non-zero number.
If you mean 21/18 then the equivalent ratio is 7/6
21:56 42:112 63:168
THey are: 16/14 and 24/21
Yes if you mean 2 1 and 18 9
7 to 2 and 21 to 3
equivalent ratios are different ratios that name the same comparison
They are: 10 to 42, 15 to 63 and 20 to 84
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).
Three equivalent ratios for 4 to 7 are 8 to 14, 12 to 21, and 16 to 28. These ratios are obtained by multiplying both terms of the original ratio by the same number. For example, multiplying 4 and 7 by 2 gives 8 and 14, while multiplying by 3 results in 12 and 21.
To determine if the ratios 14:21 and 24:36 are equivalent, we can simplify both fractions. The fraction 14:21 simplifies to 2:3 (by dividing both terms by 7), while 24:36 simplifies to 2:3 as well (by dividing both terms by 12). Since both ratios simplify to the same value, 14:21 is equivalent to 24:36.
They are called equivalent ratios.
