No, they are not equivalent ratios. To make them equivalent, The second one should be 16 to 8.

4:16

8:32=18:48=1:4, so four equivalent ratios to 8:32 are 1:4, 2:8, 3:12, and 4:16.

Yes, those two ratios are equal!

2 to 8, 3 to 12, and 4 to 16

Equivalent ratios to 4/5 can be several such as 8/10 or 16/20.

4 : 16 1 : 4 2 : 8

5:4 = 10:8 = 20:16

7 to 2, 28 to 8 and 56 to 16

6:8 12:16 9:12

1:2, 2:4, 4:8, 6:12 a equivalent ratios compares units that are the same.

No.

3 equivalent ratios for 4:8 are 75:150, 50:100 and 3:6

16 : 2 24 : 3 32 : 4

2 to 5

The two ratios, 16 to 9 and 4 to 3, are not the same number. Dividing the first number in the ratio by the second number in the ratio provides a decimal equivalent value. 16 divided by 9 does not equal 4 divided by 3. 16 to 8 and 4 to 2 however are examples of equivalent ratios. When the first number in the pair is divided by the second number in the pair, the answers are equal. Remember that equivalent ratios describe the proportion of the number of one thing to the number of another thing rather than the things themselves. So, the proportion of 16 birds to 8 birds is the same as the proportion of 4 apples to 2 apples, that is 2 to 1.

No

3 to 4

4 to 1, 4:1, or 4/1.

It could be that: 5 to 20 is equivalent 1 to 4

It could be 8 and 10

8:10 is 42:52 which is 4:5 (that's one). You can also do 43:53=12:15 (that's two) and 44:54=16:20 (that's three).

4/49 is equivalent to 0.081.
