To turn a decimal into a fraction move the decimal point two spots over (Ex: 0.34=34%). To turn a fraction into a decimal get the denominator to 100 by multiplying both the top and bottom by whatever number needed (must both be multiplied by the same number) or divide to top number into the bottom number of you can’t multiply.
        
             
        
        
        
Answer:
7.2 years
Step-by-step explanation:

where f(t) is the length and t is the number of years old
given the Mike measures 148 cm, we need to find out the age
So we plug in 148 for f(t) and solve for t

divide both sides by 200

Now subtract 1 from both sides

Divide both sides by -0.956

Now take ln on both sides



divide both sides by -0.18
t=7.2
So 7.2 years
