<p>We cross-multiply the fractions and if the obtained results are the same, then the fractions are equivalent. Cross multiplication is done by multiplying the numerator of the first fraction with the denominator of the second fraction and vice versa. In the case of \(5\over 8 \) and \(10\over 16\),<a>cross multiplication</a>is done like this:</p>
