Question

2/5 as a decimal show all work

Answer 1

0.4

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 ;

`(2)/(5)`
`((20)/(20))`

2 x 20 = 40 ;

=
`(40)/(100)`

then to convert this into a decimal, divide the numerator by the denominator

40 ÷ 100 = 0.4
