Answer: .8 or 4/5
Explanation:
You can do this a couple ways.
1) what you started is right, you can change your fraction into a decimal and divide.
2/5 = .4
.32/.4 = .8
2) you can change .32 into 32/100 and divide by 2/5
32/100 divided by 2/5
When you divide fractions, you flip the divisor and multiply
32/100 x 5/2
Multiply across
160/200
Simplify
4/5
