Answer: 18

Step-by-step explanation:

The least common denominator of $\frac{7}{9}$ and $\frac{5}{6}$ is going to be a multiple of 9 and 6. Let us list them out:

9: 9, <u>18</u>, 27, 36, 45, 54, 63, 72, 81, 90

6: 6, 12, <u>18</u>, 24, 30, 36, 42, 28, 54, 60

You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).

Morgarella [4.7K]

Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
= 0.6
100 % = 0.6 x 100
= 60 min
It takes her 60 mins or 1 hour to finish building the wall.

Hope this helps :))

What makes b in the equation true 3/8 X 8/b

Gala2k [10]

$\frac{3}{8} * \frac{8}{b} = \frac{3}{1} * \frac{1}{b}$ (I crossed simplify)

Next cross multiply;

3b = 1

b = 1/3

To check if the statement is true just substitute the value of b in the equation;

3b = 1

3(1/3) = 1

1 = 1
