To subtract fractions and decimals, we need to find a common denominator.
Given the equation -6 7/12 - 4 1/3, let's first convert the mixed numbers to improper fractions.
-6 7/12 = -(6*12 + 7)/12 = -79/12
4 1/3 = (4*3 + 1)/3 = 13/3
Now, to find a common denominator, let's consider the lowest common multiple (LCM) of 3 and 12, which is 12. Therefore, we will rewrite the fractions using 12 as the denominator.
-79/12 - 13/3
To convert -13/3 to a fraction with a denominator of 12, we multiply the numerator and denominator by 4:
-79/12 - (13*4)/(3*4)
-79/12 - 52/12
Now that the fractions have a common denominator, we can subtract them:
-79/12 - 52/12 = (-79 - 52)/12 = -131/12
Therefore, -6 7/12 - 4 1/3 is equal to -131/12.
-6 7/12 - 4 1/3
This is for subtract fractions and decimals practice
