Answer:

1/3

Step-by-step explanation:

If the hour hand moves 30° each hour and there are 12 hours on the clock, the total degree it would move in 12 hours = 12 x 36 = 360 degrees

degrees moved in 4 hours = 4 x 30 = 120

fraction = 120 / 360

to express in its simplest form, divide both numerator and the denominator by 120

= 1/3
