If 9 men can do a piece of work in 20 days, how long will it take 15 men to do the same work ?

Sagot :

9:20 is to 15:x

9 : 20 = 15 : x

9 × 15 = 20 × x

135 = 20x

[tex] \frac{135}{20} = \frac{20x}{20} [/tex]

6.75 = x

15 men will finish the same piece of work in 6.75 days or 6 days plus *18 hours or 6 to 7 days

*.75×24hours pr day=18hrs

** 9×15=20×(6.75)

135=135

tama ba? sabihan ako pag mali ha.
