Answer:
23/24
Step-by-step explanation:
I found a common denominator of 24, and then multiplied the numbers so that they would equal the common denominator. I then added all of the numbers up, to get an answer of 37/24. Finally, I subtracted 2 12/24 (which is equal to 2 1/2) to get an answer of 23/24. Because that cannot be simplified, that would be your final answer. Hope this helps :)
Answer:
The answer is 
Step-by-step explanation:
This is because there are 7 copies of the same number and that means you have to put 7 at the exponential part of it. Then you have to put the original number under the exponential spot. Therefore, the answer is .
Answer:
4 years old
Step-by-step explanation:
His sister is x years old.
Gary is 1 year less than 3 times her age, so his age is
3x - 1
His age is 11, so we can write an equation.
3x - 1 = 11
Add 1 to both sides.
3x = 12
Divide both sides by 3.
x = 4
Answer: She is 4 years old.
6/12 in decimal form is .5 because 12/6
