127/12-514/15
Using a common denominator of 60,
127/12 - 514/15 = (635 - 2056)/60
= -1421/60
Did you mean to write 1 27/12, 12 7/12, or 127/12? I assumed the latter. In any case, convert to a common denomimator. The answers will be different. For example:
12 7/12 - 5 14/15 = 12 35/60 - 5 56/60
= 11 95/60 - 5 56/60 = 6 39/60 = 5 13/20
thank you but i don't understand how you get 11 95/60 and 6 39/60 to get 5 13/20
My last step had a typing error and should be 6 13/20.
I changed 12 35/60 to 11 95/60 so I could subtract the fractions and integers separately without getting a negative fraction
To solve the expression 127/12 - 514/15, you need to find a common denominator for the fractions. The common denominator is the product of the denominators, which in this case is 12 * 15 = 180.
Let's rewrite the expression using the common denominator:
(127/12) - (514/15)
To make both fractions have the same denominator of 180, we need to multiply the numerator and denominator of the first fraction (127/12) by 15, and the numerator and denominator of the second fraction (514/15) by 12:
(127/12) * (15/15) - (514/15) * (12/12)
Now we can calculate:
(1905/180) - (6168/180)
To subtract the fractions, we subtract the numerators while keeping the denominator the same:
(1905 - 6168) / 180
Simplifying the numerator:
(-4263) / 180
Now, divide the numerator by the denominator:
-4263/180
This can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 9:
(-4263/9) / (180/9)
Simplifying further:
-473 / 20
So, the solution to the expression 127/12 - 514/15 is -473/20.
