HELP ME WITH THIS! 1/3 a = 7/9

andreyandreev [35.5K]

Answer:

a = 2 $\frac{1}{3}$

Step-by-step explanation:

Given

$\frac{1}{3}$ a = $\frac{7}{9}$

Multiply both sides by 9 ( the LCM of 3 and 9 ) to clear the fractions

3a = 7 ( divide both sides by 3 )

a = $\frac{7}{3}$ = 2 $\frac{1}{3}$

I put an answer but I’m unsure of it, any help would be much appreciated!!

Darya [45]

First you need to change 45 feet to 540 inches.

Now you can compare the two ratios:
1 : 25 and 25 : 540

We now need to change the second ratio to a unit rate:
25:540 as a unit rate would be 1 : 21.6 and this is steeper than the a 1 : 25 drop

So, your answer would be: pipe drops to much vertically to function properly
