+808 $$52\frac{1}{2}min/one..hour$$
Turn the mixed numbers into an improper fraction using this formula (can you see why it's true?):
$$a\frac{b}{c}=\frac{ac+b}{c}$$
We get:
$$52\frac{1}{2}=\frac{52*2+1}{2}=\frac{105}{2}$$
So we have 105/2 min's. We know that there's 60 min's in an hour, so we get:
$$\frac{105}{2}/60 = \frac{105}{2*60}=\frac{105}{120}=\frac{105/15}{120/15}=\frac{7}{8}$$
And this sounds correct, since 52.5 min's ≈ an hour
(105/2)/(60/1)
(105/2) * (1/60)
105/120
simplified
(105/120)/5
(21/24)/3
7/8 hours
