Question

What would happen if you divide by 2/5 instead of 4/5

Answer 1

2/5 would equal to 0.4 and 4/5 would equal to 0.8 hope that helps you

Answer 2

If you divide the original perimeter by
`\( (2)/(5) \)` (which is equivalent to multiplying by
`\( (5)/(2) \)`), you get a half perimeter of approximately 9.925 units.

If you want to find half of the perimeter by dividing it by
`\( (2)/(5) \)`, you can do the following:

`\[ \text{Half Perimeter} = (1)/(2) * \text{Perimeter} \]`

`\[ \text{Half Perimeter} = (1)/(2) * 19.85 \]`

`\[ \text{Half Perimeter} = 9.925 \]`

So, if you divide the original perimeter by
`\( (2)/(5) \)` (which is equivalent to multiplying by
`\( (5)/(2) \)`), you get a half perimeter of approximately 9.925 units.
