$$\frac{1}{4}=0.25$$
$$0.01$$ percent = $$\frac{0.01}{100} = 0.0001$$
Hence we are asked to find $$0.25 * 0.0001$$
$$25 *1 = 25$$ now to add the number of zeros after decimal and before 25 count the number of zeros in the two numbers that were multiplied.
i.e $$2$$for $$0.25$$and $$4$$ for $$0.0001$$ so altogether $$6$$
two places has already been filled by 25 hence we need four zeros after decimal
$$0.000025$$
option A

10% = 0.1
1% = 0.01
0.1% = 0.001
0.01% = 0.0001

So, 1/4 of 0.01% = 1/4 of 0.0001
= (0.25)(0.0001)
= 0.000025

Cheers,
Brent

A different approach.

Notice that 1/4 of 0.01% = 0.01% of 1/4 = 0.01% of 0.25

Now look for a pattern....

100% of 0.25 = 0.25
10% of 0.25 = 0.025
1% of 0.25 = 0.0025
0.1% of 0.25 = 0.00025
0.01% of 0.25 = 0.000025

Cheers,
Brent
