The general method is to find a number large enough to result in an integer product when you multiply the chosen number by the denominator of the fraction, then multiply the numerator by the chosen number also. In this instance, if one chooses 10 as the multiplier, the result is 700/1758, which can be reduced to lower terms by dividing both numerator and denominator by 2 to yield 350/879.
When you add a number to another number the result is their sum
The number is 121/2.
The number is 20.
