Answer:23Step-by-step explanation:The question wants us to simplify the expression 2.3/0.1. To do this, let's eliminate the denominator (0.1) by multiply by a factor that is equal to one, but has a denominator of 10 (so that 10 * 0.1 = 1). That factor would be (10/10). It is equal o 1, but will make the 0.1 disappear: (2.3/0.1)*(10/10) = (10*2.3)/(10*0.1) = 23/1 or 23Note that (10/10) is = 1, so we can multiply it by the (2.3/0.1), since multiplying by 1 does not change the correct value. It simply redistributes (correctly) the decimal point, in this case.
