Atypist takes 8 minutes to type 360 words.
how many minutes will he take to type 225 words?
a. 5 minutes
b. 4 minutes
c. 3 minutes
d. 13 minutes

A. 5 minutes

Step-by-step explanation:

We can solve this question using proportions

Let x be the number of minutes needed to type 225 words.

8 minutes = 360 words

     x          = 225 words

Cross-multiply

360 × x  =  225× 8

360 x = 1800

Divide both-side of the equation by 360

 =

(On the left-hand side of the equation, 360 at the numerator  will cancel-out 360 at the denominator, while on the right-hand side of the equation 1800 will be divided by 360)

x= 5 minutes

Therefore, it will take 5 minutes to type 225 words
