Its not that hard.
Half of the inch part is 1/2 inch which is also 4/8.
half of the 3/4 part is 3/8 you get by multiplying the denominator by 2.
Put it all back together and you get the 4/8 part and the 3/8 part so in total its 7/8 of an inch.
Monitor the Alleghany viburnum carefully in the spring. Pruning must be done right after the spring flowers die, as the buds that grow into next year's flowers develop shortly thereafter. When pruning a viburnum, the goal is to remove approximately one-third of the plant while maintaining its natural shape.
Remove the flower heads and cut back any branches that spoil the shape of the shrub to a pair of newly-sprouted leaves. Remember that removing the flower heads will preclude the formation of fruit, which can be very attractive in many viburnums. More extensive pruning should be left until late winter and early spring.
Similarly, how much does it cost to prune viburnum? While light pruning can be performed anytime throughout the year, its best to leave any major shearing or severe pruning for late winter or early spring. Of course, much of viburnum pruning depends on the variety grown too. In many cases, pruning just after flowering but before the setting of seedpods is sufficient.
