Question

what is ratio and proportion ? ​

Answer 1

Answer:

Step-by-step explanation:

• Ratio: A ratio is an comparison of quantities of the same units

• The ratio of two quantities $a$ and $b$ can be given in any one of the following ways

• (i) Symbolic form $a:b$

• (ii) Fractional form $\frac{a}{b}$

• (iii) Verbal form $a$ is to $b$

• The two quantities 'a' and 'b' are called terms of the ratio. First quantity 'a' is called first term  or antecedent and second quantity 'b' is called second term or consequent.
• Proportion: Equality of ratios is called Proportion.

Answer 2

• As we know that ratio is a comparison of two values.

• The ratio is expressed as equivalent and also as the quotient.

• The ratio formula is;$a:b$ → $\frac{a}{b}$

• An equation in which ratios are equal is known as proportion.

• As we know two ratios are equal in proportion.

• There are two types of proportion i.e direct proportion and inverse proportion.

• The proportion formula is; $a:b :: c:d$
