Reason: The latter term of the ratio is the denominator of the fraction, the former term is the numerator of the fraction, the ratio is the fractional value, and the fraction is the division, that is, the numerator is divided by the denominator, and the latter term of the ratio is certain, which means that the denominator of the fraction is certain, that is, the divisor in the division is certain. At this time, the greater the divisor, the greater the direct ratio of the value obtained by division, so the denominator is certain, and the larger the numerator, the greater the fractional value, which means that the latter term is certain.
