The ratio of boys to girls in mr. Chens class is 4 to 5. Which of the following cannot be the total number of students in mr. Ch

Rudiy27

It would be 20, because 5 plus 4 is 9 and you can multiply 9 by 2 to get 18, 9 by 3 to get 27, and 9 by 4 to get 36, but you can't multiply anything by 9 to get to 20.

Aunt Thelma planted an herb garden. She planted rosemary in 2/9 of the garden. She

Reptile [31]

Answer:

$\dfrac{17}{45}$

Step-by-step explanation:

Fraction on which Rosemary was planted $=\dfrac{2}{9}$

Fraction on which dill was planted $=\dfrac{2}{5}$

Let the fraction on which chives was planted=x

Then:

$\dfrac{2}{9}+\dfrac{2}{5}+x=1\\$Since the LCM of 9 and 5 is 45\\We multiply all through by 45\\45\left(\dfrac{2}{9}\left)+45\left(\dfrac{2}{5}\right)+45x=45(1)$\\10+18+45x=45\\45x=45-28\\45x=17\\Divide both sides by 45\\x=\dfrac{17}{45}$

The fraction of the garden on which Chives was planted is $\dfrac{17}{45}$
