Answer: 45 red marbles

Step-by-step explanation:

Using the ratios, we can create a fraction for the number of marbles.

3/5 of the bag would be red marbles, and 2/5 of the bag would be blue marbles.

(you get the 5 from adding 3+2 together)

If you take 3/5 of 75, you would get 45 red marbles.

Semmy [17]

Answer:

$Total = \frac{1}{2}$

Step-by-step explanation:

Given

$Carol = \frac{1}{8}$

$Luke = \frac{3}{8}$

Required

How far did they row together

To do this, we simply add the distance they both covered.

$Total = Carol + Luke$

This gives;

$Total = \frac{1}{8} + \frac{3}{8}$

Take LCM

$Total = \frac{1+3}{8}$

$Total = \frac{4}{8}$

Simplify

$Total = \frac{1}{2}$

<em>Hence, they both rowed 1/2 mile</em>
