Answer 1

one half is equal to the fraction of 1/2, the word of is implying multiplication, the word is means an equals, and the number is unknown so we represent that with a variable x, knowing all these, 

1/2 (one half) *(of) x (a number) =(is) 5

1/2 * x = 5

and same with the second equation

1/4(one quarter) *(of) x(number) =(is) 2

1/4 * x = 2
