Answer: 3/8
Explanation:
1/8 of the charge of a battery is consumed in 16 days. How will be consumed in 48 days?
So, to answer this question we simple have to apply a proportion:
(1/8 )/16 = charge consumed /days
For 48 days= x /48 days
(1/8 )/16 = x/48
Solving for x (charge)
[(1/8 )/16] 48 = x
3/8 =x
