What ratio is equivalent to 4/16?

A. 2:4
B. 60 TO 20
C. 8:32 **
D. 12 TO 64

Which typing time was the fastest?

A. 320 words in 8 minutes
B. 600 words in 12 minutes
C. 350 words in 10 minutes **
D. 225 words in 5 minutes

If someone could explain how to find the unit rate, that would be great!

4:16 = 8:32 -- you are correct

actually, C is the slowest.
the unit rate is words/min

350words/10min = 350/10 words/min = 35 words/min

Now try dividing the others in similar fashion

@ Steve Thank you so much!

To find the unit rate, you need to divide the given quantity by its corresponding unit.

For example, let's say you want to find the unit rate of driving distance in miles per hour. If a car travels 150 miles in 3 hours, you divide 150 by 3 to get the unit rate of 50 miles per hour.

Generally, the unit rate is given in the form of a ratio with 1 as the denominator. So in this example, the unit rate would be 50 miles per 1 hour.

To summarize, to find the unit rate, divide the given quantity by its corresponding unit.

To find the equivalent ratio for 4/16, you need to simplify the ratio by dividing both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4 and 16 is 4.

Dividing both 4 and 16 by 4 gives us 1 and 4, respectively. Therefore, the equivalent ratio to 4/16 is 1/4.

Looking at the answer choices, the correct option is C. 8:32 because if we simplify it, we get 1:4, which is equivalent to 4/16.

To determine which typing time was the fastest in words per minute (unit rate), you need to calculate the unit rate for each option. The unit rate is typically the amount of words typed in a single unit of time, usually per minute.

For option A, the unit rate is calculated by dividing the total words (320) by the total minutes (8). This gives us a unit rate of 40 words per minute (320 ÷ 8 = 40).

For option B, the unit rate is 600 ÷ 12, which equals 50 words per minute (600 ÷ 12 = 50).

For option C, the unit rate is 350 ÷ 10, which equals 35 words per minute (350 ÷ 10 = 35).

For option D, the unit rate is 225 ÷ 5, which equals 45 words per minute (225 ÷ 5 = 45).

By comparing the unit rates, the fastest typing time is option C. 350 words in 10 minutes, with a unit rate of 35 words per minute.

To find the unit rate, divide the total quantity by the given unit or time. This will give you the amount or rate per unit.
