9 5/12 - 4 2/3
A.4 1/2
B.5 1/3
C.5 1/4
D.4 3/4
9 5/12 - 4 2/3 = 8 17/12 - 4 8/12
So, now what do you think?
4 9/12
so A
it is a estimit
you got the right result, but it's not A
????
9/12 = 3/4
i somehow got -73/12
To subtract fractions, you need to have a common denominator. In this case, the common denominator is 12 since both fractions have denominators of 12.
Now let's subtract the fractions step by step:
9 5/12 - 4 2/3
First, convert the whole numbers to fractions:
9 = 9/1
4 = 4/1
9 5/12 - 4 2/3
Now, convert the mixed numbers to improper fractions:
9 5/12 becomes (9 * 12 + 5)/12 = 113/12
4 2/3 becomes (4 * 3 + 2)/3 = 14/3
Now, we can subtract the fractions:
113/12 - 14/3
To subtract the fractions, we need to find the least common denominator (LCD) of the two fractions. The LCD of 12 and 3 is 12.
Now, let's convert the fractions to have a common denominator of 12:
(113/12) = (113/12) * (1/1) = (113/12)
(14/3) = (14/3) * (4/4) = (56/12)
Now that the two fractions have a common denominator, we can subtract them:
(113/12) - (56/12) = (113 - 56)/12 = 57/12
We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which in this case is 3:
(57/3)/(12/3) = 19/4
So, the answer to the subtraction problem 9 5/12 - 4 2/3 is 19/4, which is equivalent to the mixed number 4 3/4.
Therefore, the correct answer is option D. 4 3/4.
