3/5

Step-by-step explanation:

LCM of 5,3,6 and 10=(2×3×5)=30

Now, 2/3=(2×10)/(3×10)=20/30(bydividing30/3=10)

7/10=(7×3)/(10×3)=21/30(bydividing30/10=3)

3/5=(3×6)/(5×6)=18/30(bydividing30/5=6)

5/6=(5×5)/(6×5)=25/30(bydividing30/6=5)

∴18/30 is the smallest fraction

Hence, 3/5 is the smallest fraction
