Sorry, I was wrong, I didn't work it out properly... :I
This is the answer: My way, (which is probly the hard way) is I simplified both numbers. I figured out a number which would fit into 4.25 AND 1.75 - a common denominator.
0.25 fits. I worked out how many times 0.25 fit into each of the numbers. Into 1,75 it fits 7 times. Into 4.25 it fits 17 times.
If you just need the decimal answer, 1.75 divided by 4.25 but it is really hard to turn that into a fraction.

If you understand compound fractions you might understand it this way. Convert the decimal amounts to compound fractions. Thus 4kg 250g = 4 1/4 kg = 17/4kg and the other becomes 1 3/4kg = 7/4kg
Now 7/4 divided by 17/4 equals 7/4x4/17 which equals 28/68 or in lowest form 7/17
