_48_ 2(12) Next _48_ 24 The underline stands for divide. So I'm with the two's. |

288. 12(48/2) 12(24) =288 |

To be clear....my answer is 2 |
Setting the problem = x still gives me 288 when I solve for x. 48÷2(9+3) = x x/48=1/2(9+3) x/48=1/2*12 x/48=6 x=6*48 x=288 |
Just thought of another way of saying it that might help.... My daughter is in 3rd grader and sometimes they have problems where they have to write math out in words. So, try saying it: Forty-eight divided by two times nine plus three. You have to find out what you are dividing 48 by. The key is finding out your denominator. 2 times 9+3 equals 24 Now your problem would read: 48 divided by 24. Don't know if that helps or not! :rolleyes: :) |
I think I'm still sticking with 2 as MY answer. To think, this may be my most popular thread ever on YT... ;p |
:DI actually teach this skill in 5th grade. YES, PEMDAS is used ANY time you have multiple operations however, what most people forget is even though multiplication and division are at the same level and the left to right rule applies, parentheses () outrank division. This problem is written with the 2 with the parentheses, therefore, the 2 must stay with them until it is complete. This indicates that the values must be multiplied before doing any other operation. 48÷2(9+3) is different than 48÷2X(9+3) this answer =2 this answer is =288 The 2 beside the () means you must X 2 by the answer inside to be finished. Now, thanks for making me work on my last day of spring break.:p |
Here is another example I found to look at if it helps... (4 / 2) + 4(5 - 2)^2 = (2) + 4(3)^2 = 2 + 4(9) = 2 + 36 = 38 ^2 is exponent ;) |

Another thing that might help.... Just now read some of the responses and I see that the () causes confusion. Someone said you can replace the () with * after you solve it. But, that is incorrect. The () were used to tell you to do that part first. 48/ 2(9+3) You have to solve the () first and then complete the denominator. The denominator includes the () which means you have to completely solve it before you move on. |

Yes...that is exactly what I was trying to say! Thanks Teach! :) |
I love that a math problem has 6 pages (and counting) of responses to it! |
