Methods: Multiply the ratio of the two fractions and the last item of the preceding paragraph by the least common multiple of the denominator, and then simplify it by simplifying the integer ratio. You can also find the ratio and write it out in the form of ratio.

Ratio, that is, the value obtained by comparing two numbers. The division of two similar quantities A and B can also be called ratio. Divider a is the divisor b of the previous term and the latter term of the ratio. The symbol of division is equivalent to the quotient ratio of comparison symbol and division.

To compare two nonzero numbers, it can be expressed as a fraction. The denominator is the term after the ratio, and the former is the numerator. Divided by the quotient component value, the fractional value is also a ratio. Find the ratio of two quantities of the same kind, and don't forget to unify the units. Ratio It is a number, and the result cannot be a point ratio.

Extended data

Ratio calculation knowledge point

1. The quotient obtained by dividing the former term by the latter term is called the ratio. A ratio is a value, usually expressed in fractions, decimals and integers.

2. Compared with division, the former term of ratio is equivalent to dividend, the latter term is equivalent to divisor, and the ratio is equivalent to quotient; The former term of the ratio is equivalent to numerator, the latter term is equivalent to denominator, and the ratio is equivalent to the value of fraction.

3. The basic nature of the ratio: the first term and the second term of the ratio are multiplied or divided by the same number (except 0) at the same time, and the ratio remains unchanged.
