2/5 in decimal form must show work?

2/5

= 2 ÷ 5

= 0.4

Method 1: Calculate 2÷5 using long division.
Method 2: Give the fraction a denominator of 100.
2/5 = 200/500 = (200÷5)/(500÷5) = 40/100 = 0.40

We use a decimal system so there are tenths not fifths...

2/5(2/2)=4/10 since tenths are the first digit to the right of the decimal point...

0.4

(2/5) = (2/5)(20/20) = 40/100 = (4*10^10)/(10^2)
= 4(10^(-1)) = 0.4.

0.4.

2/5 = 4/10 = 0 • 4

you can put 2/5 in decimal form by doing 2 divided by 5.
(long division required to show work)

__0
5 | 2 -------------------------> 5 goes into 2 zero times

__0.4
5 | 2.0 -------------------------------> 5 goes into 20 4 times


2/5 = 0.4



Hope this helped
