If you mean 74/80 then it is 37/40 in its lowest terms
It is around 40 GPa.
if you mean 40/64 then it is 5/8 in its lowest terms
In the absence of any other information, 40 is in its lowest terms.
If you mean 40 to 12 and 120 to 36 then they are both equivalent and in their lowest terms they are equivalent to 10 to 3
If you mean: 4x squared+12x-40 then it is (x+5)(x-2) after dividing all terms by 4
It stands for 40 volt-amperes (Volts times amps) and is a measure of power. It is equivalent to watts for a resistive load.
40 over 36 in lowest terms = 10/9 or 11/9
I'm assuming you mean 0.925 In that case, 925/1000 or 37/40 in lowest terms
You need a 40-60
It is 3/5 in its lowest terms
