(EMGV) A ratio is a comparison of two or more numbers that are usually of the same type or measurement. To compare two ratios, we have to follow these steps: Step 1: Convert each ratio into a fraction in its simplest form. We know that \({12}\) pencils cost \({72}{p}\), so if we divide \({72}\) by \({12}\) to give us the cost of one pencil: So \({1}\) pencil costs \({6}{p}\). In this article, the students get a clear vision of these two concepts with more solved examples and problems. 20 1 = 40 2 A proportion is read as "x is to y as z is to w" This relation indicates how many times one quantity is equal to the other; or in other words, ratio is a number, which expresses one quantity as a fraction of the other. Ratios and Rates . X = 5X39 / 13 = 5 X3 = 15 It expresses a fraction. The concept occurs in many places in mathematics. 12 Qs . Solution: The ratio of first two terms is 20:30 = 2:3. A part-to-part ratio states the proportion of the parts in relation to each other. You divide \(\pounds 2.85\) by \({15}\), then multiply the answer by \({20}\). Ratio and Proportion is most important for competitive exams conducting by the employers/Exam board every year. Proportion is an equation which defines that the two given ratios are equivalent to each other. Equivalent Ratios . In any proportion the first and fourth term are called as extreme terms and the second and third as middle terms. Our first ratio of the number of girls to boys is 3:5 and that of the other is 4:8, then the proportion can be written as: Here, 3 & 8 are the extremes, while 5 & 4 are the means. In the ratio a:b, we call ‘a’ as the first term or antecedent and ‘b’, the second term or consequent. Ratio and Proportion shortcut tricks are very important thing to know for your exams.

In order to convert the given ratio to Simplest Form, we should follow the following steps : – Find the HCF of both the numerator and denominator; Dividing Both numbers by their HCF; The result is the ratio in its simplest form. This means of the whole of 3, there is a part worth 1 and another part worth 2. Similarly, the ratio of lemons to oranges is 6∶8 (or 3∶4) and the ratio of oranges to the total amount of fruit is 8∶14 (or 4∶7).
