To find the answer you need to determine what they did to get from 88 down to 11

alright so, we begin with 48/88 = ?/11 right?|dw:1444149333139:dw|

we can let the question mark be X because that's the number we're trying to solve for. so 6/11 = x/11 , what would you do next?

divide by 6?

\[\frac{ 44 }{ 88} = \frac{ x }{ 11 }\] Original equation \[44 \times 11 = 88x\] ( Upon cross multiplying) \[484 = 88x\] Now simply solve for x.

88*x=?
YoloShroom
  • YoloShroom
@rainbow_rocks03 you multiply both sides by 11 to remove the fraction and you are left with 6=x
rainbow_rocks03
  • rainbow_rocks03
so 88*11 ?
Compassionate
  • Compassionate
\[x = \frac{ 484 }{ 88 }\] x = 5.5

There's no choice for 5.5 ;)

44/88 = x/11 The denominator 88 was divided by 8, therefore, the numberator must also be divided by 8 44/8 = 5.5 This method gives me 5.5 as well.

http://www.themathpage.com/alg/algebraic-fractions-2.htm My method was right, your exact solution is 5.5. Your possible choices are wrong
rainbow_rocks03
  • rainbow_rocks03
so 5.5 is the answer?

I keep getting 6.. i think you've over thought it compassionate.
YoloShroom
  • YoloShroom
Simplify the fraction first, then you can multiple both side by the same number to remove the fractions. 48/88=x/11 48/88 simplifies to 6/11 so 6/11=x/11 Multiply both sides by 11, and you remove the fraction. Leaving you with 6=x.

That's another method, but the first aforementioned method was equal. It doesn't matter if we reduce the fraction, you'll get the same number. Watch. 48/88=x/11 528/88 = x 6 = x No need to reduce. But if we solve the equation by using Equivalent Fraction to find the missing numerator, we get 5.5. This is an odd choice, indeed.

Question is a bit misleading isnt it...
Compassionate
  • Compassionate
Slightly. Read ex. 1. http://www.themathpage.com/alg/algebraic-fractions-2.htm If we have 44/88 = x/11, we can say 88 was divided by 8 to get 11. Therefore, 44 must also be divided by 8 since they are equivalent. Thus, 44/8 = 5.5 Odd, indeed.

are yall trying to help me or trying to see who did the work right?!

What math class is this for rainbow?
YoloShroom
  • YoloShroom
For your question, i believe 6 is the correct answer. @Compassionate would you agree? Since 5.5 isnt a choice
