Sophie can type 128 words in 3 minutes. How many minutes will it take her to type 576 words

Alja [10]

Answer:

13. 5 minutes

Step-by-step explanation:

This is a simple proportion problem. Make two fractions where one item is always on the top and the other on the bottom.

$\frac{3 min}{128 words} = \frac{x min}{ 576 words}$

Now, cross multiply (multiply the two numbers diagonal from each other and divide the diagonal with the x value)

576 x 3 = 1, 728

1, 728 / 128 = 13.5
