Acopy machine can print 480 copies every 4 minutes how many copies can it print in 10 minutes

10·(480:4)=10·120=1200

It can print 1200 copies in 10 minutes.

Step-by-step explanation:

This problem can be solved using a proportion.

Let x be the number of copies  that can be printed in 10 minutes.

480 copies = 4 minutes

        x         = 10 minutes

cross-multiply

4 × x  =   480 ×  10

4x = 4800

Divide both-side of the equation by 4

 =  

(On the left-hand side of the equation, 4 at the numerator will cancel-out 4 at the denominator, leaving us with just x, while on the right-hand side of the equation 4800 will be divided by 4)

x =  1200 copies.

Therefore, It can print 1200 copies in 10 minutes.
