Question: If the one year interest rate is defined as: $P_t \frac{1 + i_t}{P^e_{t+1}} = 1 + r_t$ and expected inflation is defined as: $\pi^e_{t+1} = \frac{P^e_{t+1} - P_t}{P_t}$ please solve for $1 + r_t = \frac{1 + i_t}{1 + \pi^e_{t+1}}$

If the one year interest rate is defined as:
$P_t \frac{1 + i_t}{P^e_{t+1}} = 1 + r_t$
and expected inflation is defined as:
$\pi^e_{t+1} = \frac{P^e_{t+1} - P_t}{P_t}$
please solve for
$1 + r_t = \frac{1 + i_t}{1 + \pi^e_{t+1}}$

Question:
If the one year interest rate is defined as:
Pt (1 + it)/(P^et+1) = 1 + rt
and expected inflation is defined as:
π^et+1 = (P^et+1 - Pt)/(Pt)
please solve for
1 + rt = (1 + it)/(1 + π^et+1)
