Question

One-fifth of a plank is sawn off and three-eighth for the remaining piece is then thrown away. What fraction of the original plank remains?​

Answer 1

Answer:

1/2

Hey there! heres your answer

Fraction of plank sawn off= 1/5

Fraction of the remaining part= 1-1/5= 4/5

Now, 3/8th of the remaining part= 3/8 x 4/5 = 3/10

Now, 4/5-3/10= 5/10 = 1/2
