What you can do to make a fraction equal to 1/2 is multiply the denominator and the numerator by the same number like now, I am going to multiply my denominator ( which is 2) by 2 which equals 4. Then I am going to multiply my numerator ( which is 1) by 2 which equals 2 so one of the fractions equal to 1/2 is 2/4. Now I am going to multiply 3 times 1/2 so 3×1=3, then 3×2=6. So another fraction that is equal to 1/2 is 3/6.
I hope this helped :)
