Which honey to oats ratio does not follow the pattern in the table?
5:2
10:4
15:7
20:8

Answer 1

To find out which honey to oats ratio does not follow the pattern, we can simplify each ratio:

1. 5:2 - This ratio stays as is, so it is 5/2.
2. 10:4 - Simplifying this gives 10 ÷ 2 : 4 ÷ 2 = 5:2.
3. 15:7 - This ratio stays as is, so it is 15/7.
4. 20:8 - Simplifying this gives 20 ÷ 4 : 8 ÷ 4 = 5:2.

Now we can analyze the ratios more explicitly. In terms of gaining a common understanding of the ratios:

• 5:2 can be written as 2.5 (5 divided by 2).
• 10:4 simplifies to 5:2, so it’s also 2.5.
• 15:7 would be approximately 2.14 (15 divided by 7), which is not equivalent to the others.
• 20:8 simplifies to 5:2, so it’s also 2.5.

From the analysis, we can see that 15:7 is the only ratio that does not follow the same pattern as the others, which have a ratio of 5:2 or 2.5.

Thus, the honey to oats ratio that does not follow the pattern is 15:7.
