(8x2.3)= (18.4)
(2.1x4)= (8.4)
Now you should have:
41-9+18.4-15+8.4
9+18= 27
15+8.4= 23.4
Should have:
41-27-23.4= -9.4

La mamá del profesor Ernesto tiene una bolsa con 3/4 kilogramos de arroz y guiso 2/3 de su contenido Que fracción de un kilogram
VARVARA [1.3K]

Answer: ella usó (1/2) kg de arroz para cocinar.

Step-by-step explanation:

La madre de Ernesto tenía una bolsa con 3/4 kg de arroz.

Sabemos que uso 2/3 de esa cantidad para hacer un guiso.

Entonces ella usó 2/3 de 3/4 kilogramos de arroz.

Entonces ella usó:

(2/3)*(3/4) kg de arroz.

Recordemos que esto se puede escribir como el producto entre los numeradores dividido por el producto de los denominadores:

(2*3)/(3*4) kg de arroz.

(6/12) kg de arroz

(1/2) kg de arroz.

Esto significa que ella usó (1/2) kg de arroz para cocinar.

Yes, the new coordinates would be:

R': (9,9)
P': (3,3)
Q': (9,3)

You would multiply all of the current coordinates by three (its scale factor of enlargement) to obtain these answers. Hope this helps!
