Samantha and her friends are going on a trip that is 254 7/50 miles long they already went 128 53/100 how much farther do they need to drove

Are there any answers choices or is this question your own answer?

First you should subtract the whole numbers. 
254-128=126
Now subtract the fractions. 
Multiply 7/50 by two and get 14/100 take a whole number and make it a fraction. so now you have 114/100. Subtract 53/100. 
114/100-53/100=61/100
Since we stole one from the whole number it means there is 125 instead of 126. 
Put it all together, they have 125 61/100 miles to drive.
Hope this helps!!
