Question

Is 4/10 equivalent to 1/4

Answer 1

The answer is NO

$\frac{4}{10}$ is the same as $\frac{2*2}{2*5}$

When the twos cancel out, you are left with $\frac{2}{5}$ which is not equal to $\frac{1}{4}$

Answer 2

No, if you reduced 4/10 it would be 2/5, not 1/4. The the answer to your question is no.

Also 2/5 is equivalent to 0.4 and 1/4 is equivalent to 0.25.
