Answer:

Multiply 4 by 16

Explanation:

Given

[tex]Rate = 1\ page/4\ minutes[/tex]

Required

Select the method that maintains her rate for 16 pages

To get the method for 16 pages, we simply multiply 4 by 16. This is shown below

[tex]Rate = 1\ page/4\ minutes[/tex]

Calculate the unit rate

[tex]Rate = \frac{1}{4} page/min[/tex]

[tex]Rate = 0.25 page/min[/tex]

For 16 pages, it is:

[tex]Rate = \frac{16 page}{4 min * 4}[/tex]

[tex]Rate = \frac{16 page}{4 min * 16}[/tex] -- Here, we multiply 4 by 16

[tex]Rate = \frac{16 page}{64\ min}[/tex]

[tex]Rate = \frac{16}{64} page/min[/tex]

[tex]Rate = 0.25 page/min[/tex]

See that the unit rates remain the same.

Other options will give different rates
