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.
Proportion in mathematics is different from that in life. In mathematics, it means dividing two numbers. For example, a rectangle has a length of 6, a width of 4, an aspect ratio of 6 to 4, and an aspect ratio of 4 to 6.
6÷4 Write 6:4 in the form of ratio. ":"is a ratio symbol, which is pronounced "ratio". The number before the ratio sign is called the former term of the ratio, and the number after the ratio sign is called the latter term. In this example, 6 is the first term of the ratio and 4 is the last term of the ratio.
Comparison in life is more about comparison. For example, my neighbor's little sister studies better than Xiaoming.
