Give me a brilliant if I deserve it thank you

To write 0.10190 as a fraction you have to write 0.10190 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.10190 = 0.10190/1 = 1.019/10 = 10.19/100 = 101.9/1000 = 1019/10000

And finally we have:
0.10190 as a fraction equals 1019/10000

Answer 2

Count the number of decimal places.
Number of decimal places = 4
So, we have to multiply by 10,000
( 0 at the end doesn’t give any value)
0.1019 = 0.1019/1
Now multiply the numerator and denominator by 10000
0.1019*10000/1*10000= 1019/10000
