Calculate 2/3-1/2
Add, subtract, multiply, or divide fractions and mixed numbers with step-by-step solutions.
2/3 × -1/2
Multiply the numerators together, and the denominators together:
= (2×-1)/(3×2)
= -2/6
The GCD of 2 and 6 is 2. Divide both numerator and denominator by 2:
= −(2÷2)/(6÷2)
= -1/3
= -1/3 (= -0.333333 as a decimal)
