38 145/4= 36/2=18/1
Step-by-step explanation:
First of all the fractions are in unlike fraction so we will find the L.C .M of the denominators .So L.C.M of 2 and 4 is 4. So the denominator will be 4. So,we have to convert all the denominators to four like
71/2=2*2=4,17*2=142
from which we multiply the doenominator same no. have to be multiply by numerator . And when the denominators are same we have to simply add only the numerators and then we have to convert into lowest term
