Answer:
Rule: dilation about the origin by a scale factor of 2
Step-by-step explanation:
Given
See attachment for QRST and Q'R'S'T
Required
The dilation rule
First, we calculate the scale factor (k)
From the attachment, we have:
k, is then calculated as:
<em>Hence, QRST is dilated by a factor of 2</em>

Answer:
They are equal
Step-by-step explanation:
When comparing ratios, we simply want to find out if the numbers are greater than, less than, or equal to each other. We have 4:5 and 16:20.
To find out the comparison;
Step 1: We find the LCM of the denominators ie 5 and 20, which is 20
Step 2: We divide the LCM by both sides, like this: 20÷5=4 and 20÷20=1.
Step 3: Now, multiply each ratio by the result of its individual denominator division ie

Step 4: Convert back to ratio form, we have: 16:20 and 16:20
From the above ratios, we have found out that 4:5 and 16:20 are equal when compared.
I hope this helps.
