Hence, these lines are not parallel to each other. Find the ratio of this area to the area of the given triangle. Therefore, these circles represent Also, all these fractions are equivalent. Hence, this figure represents a fraction ii Here, 4 parts are shaded out of 8 equal parts i. Also, find the value of x. At a particular point, it is exactly above a submarine floating 1200 m below the sea level.

How many questions has he attempted correctly and how many has he attempted incorrectly? Class 10 Maths Polynomials Exercise 2. Introduction to Fractions and Decimals, How Well Have You Learnt About Fractions? A triangle has 3 medians. Therefore, it represents a fraction. Answer: a In the given circles, 1 out of 2, 2 out of 4, 3 out of 6, and 4 out of 8 equal parts are shaded respectively. The water level is at the ninth step. This solution is prepared by our hard work and highly knowledgable teachers.

However, here their measures are 75º and 105º respectively. Hence, vii The given figure represents 10 shaded parts out of 10 equal parts. Move to of the page. Hence, b Here, it can be observed that 1 st, 2 nd, and 3 rd circles are representing 5, 3, and 2 shaded parts out of 5 equal parts respectively.

Is its complementary angle greater than 45° or equal to 45° or less than 45°? Hence, iv The given figure represents 1 shaded part out of 4 equal parts. The advanced version of the basic figures which is quadrilateral and parallelogram are being also mentioned on this topic, it tells us like the diagonal divides a parallelogram into 2 congruent triangles. Therefore, the fraction having the greater numerator will be greater. The ending part consists of the circle which includes various theorems in it like equal chords of a circle subtend equal angles at the center etc. Move to of the page.

Also find the coordinates of the point of division. Here, 4th square represents 6 shaded parts out of 9 equal parts. Similarly, in square ii , each row, column, and diagonal add up to give -9. Hence, viii The given figure represents 4 shaded parts out of 9 equal parts. What can you say about their perimeters? The sides of these triangles have a ratio somewhat different than 1:1. Among them, chapter 1, 3, 6 and 14 are few of the most important units for the students to learn as the topics are not only important for final exams but are also crucial in later grades.

Which figure encloses more area, the circle or the square? Click here to see or or or or or or go for Solutions or go back to main page. Hence, e Here, the denominators are same. It can be observed that two angles, even of 91º, will always add up to more than 180º. If it decreases at the rate of 2°C per hour until midnight, at what time would the temperature be 8°C below zero? Also, the sum of all interior angles of a triangle is 180º. If she has got 12 correct answers, how many questions has she attempted incorrectly? Q6 : Rita goes 20 km towards east from a point A to the point B. Hence, this figure represents a fraction iii Here, 12 parts are shaded out of 16 equal parts i.

Hence, b As the denominators of are same, the fraction having the greater numerator will be greater. Hence, v The given figure represents 3 shaded parts out of 7 equal parts. Click here to see or or or or or or go for Solutions or go back to main page. Answer: If these triangles are congruent, then the corresponding angles and sides will be equal to each other. Out of two perimeters, which is greater? Move to of the page. Here, 2nd square represents 4 shaded parts out of 9 equal parts. Therefore, the fraction having the greater numerator will be greater.

Therefore, it represents a fraction. This makes the student understand better and give them an option to choose the solution more suitable to them. This would ultimately lead to a good score on their board exam. Hence, c Here, it can be observed that 1 st, 2 nd, and 3 rd rectangles are representing 2, 3, and 5 shaded parts out of 6 equal parts respectively. Answer : Since the amount withdrawn is represented by a negative integer, the amount deposited will be represented by a positive integer. Therefore, it represents a fraction.
