5 out of 8 and 3 out of 10
The least common multiple of 8 and 10 should be 40
5 out of 8 times 5 is 25 out of 40
3 out of 10 times 4 is 12 out of 40
One out of two, three out of four and five out of eight
If the denominator is 8.2, it becomes "4 / 8", 3 / 4 becomes "6 / 8", and 5 / 8 remains unchanged, then OK
Is the least common denominator the same as the common denominator
Why not
It's not the same
