Question

Which expressions are equivalent to the expression 24 ÷ (12 – 4)?

Choose exactly two answers that are correct.

A: 18-5 times 3
B: 3 + 6 ÷ 3
C:36 ÷ (10 + 2)
D:12 – 4 ÷ 2 – 3

Answer 1

whoever answers first will get a medal and I will become a fan

Answer 2

ok so first we do 12-4 which is 8. 24 divided by 8 is 3. So the answer has to equal the three listed below...

Answer 3

18-5=13 13*3 does not equal 3 so its not A

Answer 4

a
c

Answer 5

3+6=9. 9divided by 3 equals 3!

so the answer must be B right?

Answer 6

I think it is b, c, d.......... right?

Answer 7

wait I can't pick more than 2 so it is not b c d

Answer 8

@bantaray The multiplication takes precedence over subtraction and so A) is 18-5 times 3 = 18 - 15 = 3

Answer 9

the answer is B and C @Ilovecake

Answer 10

Ok thanks @bantaray

Answer 11

The answer is A and C.

B: 3 + 6 ÷ 3
Division has to be done before addition so 3 + 6 ÷ 3 = 3 + 2 = 5.

Remember the order of operations: PEDMAS
P: Parenthesis
E: Exponentiation
D: Division
M: Multiplication
A: Addition
S: Subtraction

Answer 12

So @aum, there should be three right answers..

Answer 13

Isn't it PEMDAS

Answer 14

@bantaray no there can only be 2 right answers................

Answer 15

Both are same. D and M have the same level of precedence and so either one can be done before the other.
A and S also has the same level of precedence and so either one can be done before the other.

Answer 16

you're right, I see my mistake! It is A and C.. My bad :)

Answer 17

So PEMDAS or PEDMAS both will work because M and D are at the same level of precedence.

Answer 18

i said a,c
