miles
<u><em>Explanation:</em></u>
<u>To convert a decimal to a fraction:</u>
1- Write the decimal as a fraction whose denominator is 1
2- Multiply both numerator and denominator by multiples of 10 to eliminate the decimal point
3- Simplify the fraction you have
<u>Now, for the given problem:</u>
<u>The given decimal is 0.62, following the above steps:</u>
<u>Step 1: </u>

<u>Step 2:</u>
We have two digits after the decimal point, so to eliminate the decimal point, we will multiply the numerator and the denominator by 100

<u>Step 3:</u>
We can note that, in the fraction obtained from step 2, both the numerator and the denominator are divisible by 2, so we simplify as follows:

Hope this helps :)
Answer:
1/3 I think I did the math and if that's not right try 1/3:1/4 (<--ratio)
Step-by-step explanation:
A) 0.4, to do this just do 40/100
B) x + 0.4x= retail price
C) 56*0.4= 22.4, so add this to the original price for a total of $78.4
D) Just like in part C, 56*0.4= $22.4
