Attention!!! If you skip an example, it is counted as a not solved and you can not come back to it.

For reduction of fractions to the least common denominator you should:

• find the least common multiple of the denominators [it will be the least common denominator];
• divide the least common denominator into denominators of the given fractions [it means to find for each fraction an additional multiplier];
• to multiply numerator and denominators of each fraction by its additional multiplier.
