Answer:
C
Step-by-step explanation:
Use the pythagorean theorem
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²
5 = c
First we must change these numbers to improper fractions:


So then we set it up:
÷ 
When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:

Then we solve:

Then if we divide the numerator and the denominator by 9, we get:
or, in mixed-number form,
.
I think the answer is d or b if im wrong sorry hope this helped tho :p
