converted to fraction in lowest terms is 
<em><u>Solution:</u></em>
Given that we have to convert
to fraction in lowest terms
Let us first convert the mixed fraction 
Multiply the whole number part by the fraction's denominator.
Add that to the numerator.
Then write the result on top of the denominator.
Therefore,


Now convert 77.5 % to fraction
So we have to convert percentage to fraction
Divide the percentage by 100 to get a decimal number

Use that decimal number as the numerator of a fraction. Put a 1 in the denominator of the fraction
Count the number of places to the right of the decimal. If you have x decimal places then multiply numerator and denominator by 

Simplify and reduce the fraction to lowest terms

Thus the given percentage is converted to fraction in lowest terms
The restrictions would be possible x values that could make the function equal 0.
Step 1: Write the amount of savings in equation
Linda's savings: s=1.55d
Tyron's savings: m=3.90d
Step 2: Add on the extra days to Linda's savings
Linda's savings s=1.55d+3(1.55)
Step 4: Simplify equation
s=1.55d+3(1.55)
s=1.55d+4.66
Step 5: Substitute numbers for d days until Tyron's m savings is greater than Linda's s saving
m=3.90d s=1.55(2)+4.66
m=3.90(2) s=3.10+4.66
m=7.80 s=7.76
On Tyron's second day he will have more money in his savings than Linda does.
Answer: 40%
Step-by-step explanation: all percents add to 100%, so 40%+20%=60%, and 100%-60%=40%
