valina [46]

Answer:

La profesora debe comprar 8 manzanas para reponer la cesta de frutas.

Step-by-step explanation:

La profesora debe reponer la cesta de frutas por la cantidad de manzanas que se encuentran dañadas. La cantidad de manzanas dañadas es igual a las dos séptimas partes del total de manzanas. Es decir:

x = \frac{2}{7} \times (28\,manzanas)

x = \frac{56\,manzanas}{7}

x = 8\,manzanas

La profesora debe comprar 8 manzanas para reponer la cesta de frutas.

(3 8) 1 = 3 (8 1) A.True B.False
Zepler [3.9K]
Hi there!

This is pretty easy if you remember PEMDAS.

P = Parenthesis, and that's all we have in our equation so we'll work out what's in the parenthesis first.

(3×8) = 24. Then we go to the outside of the parenthesis and multiply 24 by whatever is on the outside.
24×1 =, well, 24.

Now we can go to the other side.

(8×1) = 8
8×3 = 24

Wow! Wouldja look at that? We are left with

24 = 24

The correct answer is A) True.

Hope this helps! <3
