Solve the following exercise:
To solve the problem of subtracting the fractions and , we follow these steps:
The fraction is converted by determining what number we multiply 4 by to get 12 (which is 3). Thus, multiply both the numerator and the denominator by 3:
.
The fraction is converted by determining what number we multiply 6 by to get 12 (which is 2). Hence, multiply both the numerator and the denominator by 2:
.
.
The solution is the fraction .
In conclusion, the answer to this problem is .
Solve the following exercise:
\( \frac{3}{2}-\frac{1}{2}=\text{?} \)
List the multiples of each number: 4: 4, 8, 12, 16... and 6: 6, 12, 18, 24... The smallest number that appears in both lists is 12, so that's your LCD!
You never subtract denominators in fraction subtraction! The denominator tells you the size of each piece. Only subtract the numerators (the number of pieces) once you have the same denominator.
That's okay! is already a proper fraction, but if you got something like , you could convert it to or simplify to .
is already in lowest terms because 7 and 12 share no common factors other than 1. Always check if you can simplify, but don't worry if it's already simplified!
Start small! For 4 and 6, try 12 first (4×3 and 6×2). If that works, great! You don't need to use larger numbers like 24 even though they're also common multiples.
