Question

Sharko had 300 pens. The ratio of the number of pens Sharko had to the number of pens Kyle had was 6 : 11. How many pens must Kyle give to Sharko such that both of them will have equal number of pens?

Answer 1

125

Explanation:

300/6=50

50 x 11=550

550 + 300=850

6+11=17

850/17=50

trail and error

50: 300+50=350 and 550-50=500 X

100:300+100=400 and 550-100=450 X

150:300+150=450 and 550 -150=400 X

125:300+125=425 and 550-125=425

So kyle must give 125 pens to Sharko
