7 1/12  -  2 3/4
First we have to change mixed numbers to improper fractions
7 1/12  =  7 x 12 + 1 = 85   85/12
2 3/4  =  2 x 4 + 3 =  11     11/4
 85/12 - 11/4
Now we need to find the LCD (least common denominator) for 4 and 12
4, 8, 12
12
12 is our LCD, so it becomes our new denominator
85/12 would stay the same because the denominator wasn't changed but for 11/4 our new denominator is 12, so our fraction will change.
11/4  =  33/12 
4 goes into 12, 3 times. What you do to the bottom, you do to the top.
3 x 11 = 33
3 x 4 = 12
So, our new fraction is 33/12.  Now we subtract
85/12  -  33/12  =  52/12
Now we convert back to a mixed number
52 ÷ 12 = 4 4/12 reduce 
4 1/3
Hope this helps.

Answer:
The best estimate for the money in Karita's account now is $151.
Step-by-step explanation:
Given:
Karita had $138.72 in her checking account. 
She wrote checks for $45.23 and $18.00. 
Then she made a deposit of $75.85 into her account.
Now, to find the best estimate for the money in Karita's account now.
<em>Initial account = $138.72.</em>
<em>Deducted amount = $45.23+$18.00=$63.23.</em>
So, the amount after deduction:
$138.72 - $63.23 = $75.49.
Now, the amount after deposit:
$75.49 + $75.85 = $151.34.
Therefore, the best estimate for the money in Karita's account now is $151.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The equality of bases property says powers of the same base will be equal if and only if the powers are equal. This property is used to solve exponential equations.

<em>Additional comment</em>
Equating the exponents is fully equivalent to taking the logarithm of both sides of the equation, to that base.
