1/5 x 1/5 + 4/25 = ?

Explanation

In mathematics a fraction represents any number of equal parts. The numerator represents the number of equal parts, and the denominator, which cannot be zero, indicates how many of those parts make up a unit or a whole. For example, in the fraction 3/4, the numerator, 3, tells us that the fraction represents 3 equal parts, and the denominator, 4, tells us that 4 parts make up a whole. The word comes from the Latin "fractus", which means "broken".
