Question

(5 1/4) divided by (-2 1/4) need HELP tnx

Answer 1

We must transform the mixed numbers to the improper fraction.

$5\dfrac{1}{4}=\dfrac{5\cdot4+1}{4}=\dfrac{21}{4}\\\\-2\dfrac{1}{4}=-\dfrac{2\cdot4+1}{4}=\dfrac{9}{4}$

Calculate a product:

$\left(5\dfrac{1}{4}\right):\left(-2\dfrac{1}{4}\right)=\dfrac{21}{4}:\left(-\dfrac{9}{4}\right)=-\dfrac{21}{\not4_1}\cdot\dfrac{\not4^1}{9}=-\dfrac{21:3}{9:3}=-\dfrac{7}{3}$

Answer 2

Answer:

-7/6

Step-by-step explanation:

That'd be 21/4 divided by -9/2, or, equivalently, 21/4 times -2/9.

From this we get -42/36, which, when reduced, yields -7/6.
