1 over 2 or in decimal form: .5
It is: 3 and 1/5 = 3.2 as a decimal In general, a number N over 5 is written as a decimal by doubling it (worry about the decimal point). Examples: 1/5 = .2 2/5 = .4 5/5 = 1.0 So 3/5 would be .6 and 1/5 would be .2
The answer is 0.2 This is because 1/5 is equal to 2/10 and the first decimal place is the tenths column therefore it is 0.21 over 5 written as a decimal = 0.21/5:1 ÷ 5= 0.2 in decimal
2.2
1/5 = 2/10 so answer is 4.2
