Write in simplest form

Gnoma [55]

Find the commomon denominator of 6 and 5.

It's 6 · 5 = 30.

$\dfrac{5}{6}=\dfrac{5\cdot5}{6\cdot5}=\dfrac{25}{30}\\\\\dfrac{1}{5}=\dfrac{1\cdot6}{5\cdot6}=\dfrac{6}{30}$

$\left(\dfrac{5}{6}-\dfrac{1}{5}\right)\div\dfrac{4}{5}=\left(\dfrac{25}{30}-\dfrac{6}{30}\right)\div\dfrac{4}{5}=\dfrac{25-6}{30}\div\dfrac{4}{5}=\dfrac{19}{30}\div\dfrac{4}{5}$

Divide by fraction is the same like multiply by reciprocal of this fraction:

$=\dfrac{19}{30}\cdot\dfrac{5}{4}=\dfrac{19}{6}\cdot\dfrac{1}{4}=\dfrac{19}{24}$

PLEASE ANSWER NUMBER 32!!!

Leni [432]

Answer:

N < -3

Step-by-step explanation:

first off, simply, then subtract the 9s from both sides.

5n < -6 -9

Simplify -6 -9 to -15 , Which gives you

5n < -15

then, divide both sides by 5.

n < 15/5

Simplify 15/5 to 3, Which give you

N < -3

here is your answer.

N < -3
