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