Answer:
0.4
Step-by-step explanation:
to convert from a fraction to a decimal, we first have to make the denominator 100
we know that 5 goes into 100 20 times ;
100 ÷ 5 = 20 ;
then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;
[tex]\frac{2}{5}[/tex] [tex](\frac{20}{20})[/tex]
2 x 20 = 40 ;
= [tex]\frac{40}{100}[/tex]
then to convert this into a decimal, divide the numerator by the denominator
40 ÷ 100 = 0.4
