Explanation:

Step1: Set up ratio - paint problem

Let $x$ be the amount of red paint. The ratio of red to yellow is $\frac{3}{5}=\frac{x}{20}$. Cross - multiply: $5x = 3\times20$.

Step2: Solve for $x$

$5x=60$, so $x = 12$ oz.

Step3: Set up ratio - lawnmower problem

The factory produces 12 lawnmowers in 8 hours. The rate is $\frac{12}{8}=\frac{3}{2}$ lawnmowers per hour. Let $t$ be the time to produce 30 lawnmowers. Then $\frac{3}{2}=\frac{30}{t}$, cross - multiply: $3t=60$, so $t = 20$ h.

Step4: Set up ratio - weight problem

If 10 lb on Earth is 4 lb on Mars, let $y$ be the weight on Mars for 95 lb on Earth. Then $\frac{4}{10}=\frac{y}{95}$, cross - multiply: $10y = 4\times95=380$, so $y = 38$ lb.

Step5: Set up ratio - juice problem

The ratio of orange juice to pineapple juice is $\frac{4}{3}=\frac{64}{z}$. Cross - multiply: $4z=64\times3 = 192$, so $z = 48$ oz.

Step6: Set up ratio - cookie problem

For 60 cookies, 4 cups of flour are needed. Let $w$ be the flour for 90 cookies. The ratio is $\frac{4}{60}=\frac{w}{90}$, cross - multiply: $60w=4\times90 = 360$, so $w = 6$ cups.

Step7: Set up ratio - reading problem

Jose reads 7 pages in 5 minutes. Let $m$ be the time to read 175 pages. The ratio is $\frac{7}{5}=\frac{175}{m}$, cross - multiply: $7m=175\times5=875$, so $m = 125$ min.

Step8: Set up ratio - heart rate problem

The heart beats 12 times in 5 seconds. Let $b$ be the beats per minute (60 seconds). The ratio is $\frac{12}{5}=\frac{b}{60}$, cross - multiply: $5b=12\times60 = 720$, so $b = 144$ times per minute.

Step9: Set up ratio - calorie problem

If 8 oz of hot fudge has 1200 calories, let $c$ be the calories in 3 oz. The ratio is $\frac{1200}{8}=\frac{c}{3}$, cross - multiply: $8c=1200\times3 = 3600$, so $c = 450$ cal.

Step10: Set up ratio - college ratio problem

The ratio of men to women is $\frac{6}{5}=\frac{1500}{u}$. Cross - multiply: $6u=1500\times5 = 7500$, so $u = 1250$ women.

Step11: Set up ratio - window problem

The height - to - length ratio of the window is $\frac{2}{25}=\frac{24}{l}$. Cross - multiply: $2l=24\times25 = 600$, so $l = 300$ ft.
