Sometimes a dilation is an enlargement, and sometimes it is a reduction. Explain what types of numbers for scale factors causes each.

Question

anonymous · Answer

Just as with a dilation, when you multiply a number by something, it can either get larger or smaller. For example, if I have 16, what numbers can I multiply it by to make it smaller? larger?

anonymous · Answer

What is confusing you?

anonymous · Answer

What kind of numbers make it smaller?

anonymous · Answer

If I multiply a number by 1, it remains the same. What happens if I multiply by a number greater than 1?

anonymous · Answer

If I multiply 16 by 1.1, what do I get? Is it larger or smaller than 16?

anonymous · Answer

I'm less concerned with helping you how to write it(right now) than making sure you understand the concept. Describe what you understand about the problem now, taking into account what I've said.

anonymous · Answer

If your scale factor has absolute value greater than 1, the dilation is an enlargement.

anonymous · Answer

That would be correct. What would make it smaller?

anonymous · Answer

We know what happens to values greater than 1, and that are 1, what's left?

anonymous · Answer

What's between 0 and 1?

anonymous · Answer

1/6, 1/3, 1/2, 2/3, 5/6

anonymous · Answer

What happens when you multiply by those, or use those as scale factors?

anonymous · Answer

how would I write this?

ranga · Answer

There are 3 cases to consider: 
1) scale factor has absolute value greater than 1 ==> Enlargement 
2) scale factor has absolute value equal to 1 ==> No change. 
3) scale factor has absolute value less than 1 ==> Reduction

ranga · Answer

I just typed the remaining two cases based on your earlier answer:
"If your scale factor has absolute value greater than 1, the dilation is an enlargement."

I don't want to waste my time here anymore.
