Answer:
62.5%
Step-by-step explanation:
Notice that the rate of 5 out of 8 couples, can be also written in quotient form (to actually represent a rate) as: 5/8
That quotient gives us a number that can be written in percent form by multiplying it by 100:
[tex]\frac{5}{8}= 0.625\\0.625\,*\,100=62.5[/tex]
Therefore this rate is equivalent to 62.5%
