So here first you have to have same denominators to subtract and add.
to make same denominator you have to multiply something to them which meets up to their lowest common multiple (LCM). so here the easiest thing is multiply each denominator to the other but remember you have to multiply them to the numerator too.
3×9/5×9-2×5/9×5
so it becomes
27/45-10/45
17/45
as you cant bring to its simplest form since the answer in a prime no. leave it like that.
NO. They are not.
We can prove this by turning those numbers into fractions:
16 / 14 = 1.1428 ; 64 / 60 = 1.0667
Or simply:
64 / 16 = 4
60 / 14 = 4.29
To get the equivalent of 16 to 14; we must multiply both numbers by 4.
16 * 4 = 64
14 * 4 = 56
The equivalent of 16 to 14 is 64 to 56.
