4112

Explanation:

I would first check to see if anything would cancel out.
127372

All the numbers are prime, so there is nothing to cancel out (aka nothing is the same on top and bottom, and 7 can not be divided by anything on the bottom)

So without reducing ...all that's left to do is multiply.

Multiply all the number across the top to get the numerator.
1×7×7=49

Now multiply all the bottom numbers to get the new denominator
2×3×2=12

Put it together you get an improper fraction of 4912

You know it's improper because the top is bigger than the bottom. (Remember if a young lady is bigger up top it's easy to be improper)

Now to get it into standard form use division. 12 goes into 49 4 times with 1 leftover So you get a final answer of 4112
