Hello from MrBillDoesMath!
Answer:
t = i /(Pr)
Discussion:
i = Prt => (divide both sides by "Pr")
i/(Pr) = (Prt)/(Pr)
= (Pr)t/(Pr)
= t (as (Pr)/(Pr) = 1)
Thank you,
MrB
Well, first of all, you have to change the mixed fraction to a proper fraction. So you have to multiply 25 by 1 and add the answer to 2, and use it as the numerator, with the denominator remaining the same. So;
27/25
As a decimal, this fraction will be 1.08. Hope i helped. Have a nice day.
167.78 / 189.35 = .88608 * 100 = 88.6083971481 round it you get 89
