Step-by-step explanation:

First break it down

42= 40 & 2

27= 20 & 7

  • Then times 40 & 20 to get 800
  • 20 x 2 to get 40
  • 40 x 7 to get 280
  • 7 x 2 to get 14

Now add them all together.

800 40 1080

+280 +14 + 54

---------- ------- ---------

1080 + 54 = 1134

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
