Hi I really need help with a and b. thank you

A) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number. 
\frac{27}{45} = \frac{x}{5}

Next, you would cross multiply. 
135 = 45x

Now, the last step would be to isolate the x. To do this, you would divide both sides by 45. 
3 = x

\frac{27}{45} = \frac{3}{5}

b) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number. 
\frac{2}{6} = \frac{3}{x}
Next, you would cross multiply. 
18 = 2x

Now, the last step would be to isolate the x. To do this, you would divide both sides by 2. 
9 = x

\frac{2}{6} =\frac{3}{9}

I hope this helps!

A weed called the raindrop vine is known for growing at a very fast rate. It can grow up to 0.75 feet per day. How fast in inche
viktelen [127]

R = rate of growth of raindrop vine = 0.75 feet/day

we know that :  1 feet = 12 inches

1 day = 24 hours

replacing the units accordingly in the above expression for rate of growth of raindrop vine

R = 0.75 (feet/day)  (12 inches/1 feet) (1 day/24 hours)

R = (0.75 x 12 /24) (inches/hour)

R = 0.375 inches/hour
