Answer:


(45)/(75) black marbles.

Explanation:

A jar contains 75 marbles.


(3)/(5) of the marbles are black.

We will multiply
(3)/(5) by 75 to get the number of black marbles.

The number of black marbles =
(3)/(5) × 75

=
(3)/(1) × 15

= 45 marbles

45 marbles are black out of 75 marbles. so we can write
(45)/(75) black marbles.
