Wich equation gives the number of 1/3 inches that are in 5/6 inches
lara31 [8.8K]

Hello from MrBillDoesMath!

Answer:

(1/3) x = (5/6)


Discussion:

I think you are asking for this equation:

(1/3) x = (5/6) =>            multiply both sides by 3

(1/3) 3 x = (5/6) 3 =>      as (1/3) *3 = 1

x = 5*3/6

x= 15/6

x = 5/2 = 2.5

Thank you,

MrB
