Question

Is 4 Fifths Greater than 3 tenths?

Answer 1

No. Take 5 and multiply it with 6 and multiply 4 with 6. equals 24 30. 
Now, three multiplied by 3 equals 9. 10 x 3=30. 
comparison: 24  30> 3  30
the denominator is equal, it is easier like that!
maybe this is wrong but, hope this helps!

Answer 2

Yes, because 4/5 is really 8/10 which is greater than 3/10.
