In this item, it is unfortunate that a figure, drawing, or illustration is not given. To be able to answer this, it is assumed that these segments are collinear. Points L, M, and N are collinear, and that L lies between MN.
The length of the whole segment MN is the sum of the length of the subsegments, LN and LM. This can be mathematically expressed, LN + LM = MN
We are given with the lengths of the smalller segments and substituting the known values, MN = 54 + 31 MN = 85
Multiply the whole number by the denominator so 3x8=24 and then add the numerator so 24+7=31. 31 will be your new numerator over 8. Therefore the improper fraction will be 31/8.
