At the hardware store 1/2 of the nails are size 2d and 1/3 of the nails are size 4d. what fraction of the nails are either size 2d or 4d?

Alright so let’s turn these fractions into fractions with common denominator
So a common denominator for both of them is 6
So 1/2 x 3/3 = 3/6
1/3 x 2/2 = 2/6
2/6 +3/6=5/6
So 5/6 if the nails are either 2d or 4d
