Question

leon wrote an expression that is equivalent to (30 + 6) ÷ 12 which expression could be the one Leon wrote A. 36÷3 • 4 B.(3 • 3 • 4) ÷ 4 • 3 C. 5 • 6+2 • 3 ÷ 3 • 2 • 2D. (3 • 3 • 2 • 2) ÷ (3 • 2 • 2) and explain why you chose A, B, C, or D

Answer 1

First lets simplify;

(30 + 6) ÷ 12

Using PEMDAS

36 ÷ 12 = 3

Lets check option A

Using PEMDAS

36÷3 • 4 = 12 • 4 = 48

This means A is not the correct option

We move to B.

(3 • 3 • 4) ÷ 4 • 3

Using PEMDAS

we solve the bracket

36 ÷ 4 • 3 = 9 • 3 =27

B is not the option.

We move to C

5 • 6+2 • 3 ÷ 3 • 2 • 2

Using PEMDAS

30 + 6÷ 3 • 2 • 2

= 30 + 2 • 2 • 2

=30 +8

=38

C is not the option

We move to option D

(3 • 3 • 2 • 2) ÷ (3 • 2 • 2)

Using PEMDAS, we will solve the parenthesis first

36 ÷ 12 = 3

Therefore option D is the correct options.

Option D is equivalent to (30 + 6) ÷ 12
