Mathematics - Ratios and Proportions - Equivalent ratios - Ratio Table Builder

Show a ratio table with the initial ratio (e.g., 2:5). The student fills in the table by scaling up (×2, ×3, ×4, ×5) and sees the bar chart of both quantities growing proportionally. The bars maintain the same relative height. Then try scaling down (from 12:30, divide to find the simplest form 2:5).
