what ratios are equivalent to 21:6 and 7:2

Answer 1

To find ratios that are equivalent to 21:6, we can simplify this ratio by dividing both terms by their greatest common divisor, which is 3.

21 ÷ 3 = 7
6 ÷ 3 = 2

So, the simplified ratio is 7:2.
Therefore, the ratio 7:2 is equivalent to 21:6.

Similarly, to find ratios that are equivalent to 7:2, we can simplify this ratio by dividing both terms by their greatest common divisor, which is 1 (since 7 and 2 are already relatively prime).

So, the simplified ratio is 7:2.
Therefore, the ratio 7:2 is equivalent to itself.
