Since 1/6 of the day was spent in the flower bed and 2/3 of that was spreading mulch, we need to find 2/3 of 1/6 to find out how much of the day was spreading the mulch.
In math "of" means times "is" means equals
2/3 of 1/6 is
translates to
2/3 x 1/6 =
Now we just multiply the numerators across and denominators across then reduce if possible...
