The statement 鈥�$\frac{13}{20}-\frac{2}{5}$.鈥�

When two fractions with different denominators are subtracted then the two unlike fractions, are converted into like fractions by multiplying the denominators with a common factor of their lowest common multiple (LCM).

Consider the provided statement 鈥�$\frac{13}{20}-\frac{2}{5}$.鈥�

Recall that when two fractions with different denominators are subtracted then the two unlike fractions, are converted into like fractions by multiplying the denominators with a common factor of their lowest common multiple (LCM).

LCM of 20 and 5 is 20.

So, multiply $\frac{2}{5}$by 4 in both numerator and denominator,

Thus, the given expression can be simplified as,

$\frac{13}{20}-\frac{2}{5}=\frac{13}{20}-\frac{2脳4}{5脳4}$

$\frac{13}{20}-\frac{2}{5}=\frac{13}{20}-\frac{8}{20}$

$\frac{13}{20}-\frac{2}{5}=\frac{13-8}{20}$

$\frac{13}{20}-\frac{2}{5}=\frac{5}{20}$

Now, 5 can be expressed as the product of 5 and 1.

20 can be expressed as the product of 5 and 4.

So, $\frac{5}{20}$can be simplified as,

$\frac{5}{20}=\frac{5脳1}{5脳4}$

Striking off the common terms, we get,

$\frac{5}{20}=\frac{1}{4}$

Hence, the simplified form of $\frac{13}{20}-\frac{2}{5}$is $\frac{1}{4}$.
