Answer:
2/5 =0.4
Explanation:
Decimals are one of the method of representation of fractions in which there is power of 10 in the denominator of the fraction. They are 10,100,1000,10,000 ,100,0000 and so
Example = 1/10 = 0.1
1/100 = 0.01
1/1000 = 0.001
In 2/5 we have to make the denominator 10
since in denominator there is five , can be made 10 by multiplying it by 2
2/2 = 1 and 1* x = x , hence if we multiply numerator and denominator by 2 it won't change the fraction.
2/5×2/2=2×2/5×2=4/10=0.4
Thus, 2/5 =0.4 in decimal form.
