Solve the problem. make sure your answer is in simplest form. 3/10 x 5/12

When multiplying fractions you just multiply the numerators together:
3X5 = 15

Then you multiply the denominators together:
10X12 = 120

So 15/120.   Now simplify
Divide both by 15
1/8

I chose 15 because I knew that off the top of my head.  If you didn't know that start with what you do know. For example

15/120 - you can divide by 5
3/24 - you can divide by 3
1/8
You still get the same answer.  If you notice dividing by 5 and then by 3 is the same as dividing by 15

La reta correcta es 0.125.

solo multiplicas 0.3 x 0.416 = 0.125

el 0.3 es el resultado de dividir 3/10 y el 0.416 es el resultado de dividir 5/12

Espero haberte ayudado.
