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
