6th Class Mathematics Ratio and Proportion

  • question_answer 3) See the figure and find the ratio of (a) Number of triangles to the number of circles inside the rectangle.           (b) Number of squares to all the figures    inside the rectangle.                  (c) Number of circles to all the figures inside the rectangle. TIPS Firstly, find the number of triangles, squares and circles from given figure, then find the required ratio.                                                

    Answer:

                    In the given figure, Number of triangles = 3; Number of squares = 2 Number of circles = 2 \[\therefore \] Total number of figures = 3 + 2 + 2 = 7 (a) Required ratio of number of triangles to the number of circles \[\text{=}\frac{\text{Number}\,\text{of}\,\text{triangles}}{\text{Number}\,\text{of}\,\text{circles}}=\frac{3}{2}=3:2\] (b) Required ratio of number of squares to all the figures \[\text{=}\frac{\text{Number}\,\text{of}\,\text{squares}}{\text{Total}\,\text{number}\,\text{of}\,\text{figures}\,}\text{=}\frac{2}{7}\text{=2:7}\] (c) Required ratio of number of circles to all the figures \[\text{=}\frac{\text{Number}\,\text{of}\,\text{circels}}{\text{Total}\,\text{number}\,\text{of}\,\text{figures}\,}\text{=}\frac{\text{2}}{\text{7}}\text{=2:7}\]
