Question

What is 2/5 as a decimal

Answer 1

Think of 5 as being 1.00 and you need to split it into five equal pieces. Each "piece" will be worth 0.20 because 0.2+0.2+0.2+0.2+0.2 = 1 so,

2/5 = 0.4

Answer 2

To change a fraction to a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction, while the denominator is the bottom part of the fraction. 

2 ÷ 5 = 0.4

Thus, $\frac{2}{5}$ as a decimal would be $0.4$
