Answer:
\(\frac{45}{75}\) black marbles.
Step-by-step explanation:
A jar contains 75 marbles.
\(\frac{3}{5}\) of the marbles are black.
We will multiply \(\frac{3}{5}\) by 75 to get the number of black marbles.
The number of black marbles = \(\frac{3}{5}\) × 75
= \(\frac{3}{1}\) × 15
= 45 marbles
45 marbles are black out of 75 marbles. so we can write \(\frac{45}{75}\) black marbles.
