one tenth times two tenths
2/10's because you multiply the denominator by the denominator and the numirator by the numirator wich is 1*2=2
and the denominators if the same would again stay the same giving you 2/10's
The denominator needs to be multiplied too...
Hang on just a sec ILT
1/10 * 2/10 = 2/100 = 1/50
When you MULTIPLY fractions the numerator AND denominator get multiplied ...alike or not.
