From the give information, 15/28 of the writing utensils are black pens

From the question, we are to determine what fraction of the writing utensils are black pens

From the give information,

5/7 of the writing utensils are pens

and

3/4 of the pens are black pens

∴ 3/4 of 5/7 of the writing utensils are black pens

3/4 of 5/7 = 15/28

Hence, 15/28 of the writing utensils are black pens
