Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(10, 3) = 1. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - five multiplied by two thirds = ten thirds.
Multiple: 2 * 1/
2
= 2 · 1/
1 · 2
= 2/
2
= 1 · 2/
1 · 2
= 1
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(2, 2) = 2. In the next intermediate step , cancel by a common factor of 2 gives 1/
1
.
In words - two multiplied by one half = one.
Subtract: the result of step No. 1 - the result of step No. 2 = 10/

- 1 · 3/
1 · 3
= 10/

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(3, 1) = 3. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 1 = 3. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - ten thirds minus one = seven thirds.
