Well, this can be interpreted as 1/10 ÷ 6/19
Whenever you are dividing fractions, you have to change the division sign to a multiplication sign and turn the fraction on the right upside down. By this, i mean;
1/10 × 19/6
That will be;
1x19/10x6
19/60. So your answer is 19/60. And it is already in it's simplest form because nothing else can divide the two numbers. Hope i helped. Have a nice day. If you have any more problems on this, let me know and i will be glad to help.
