Ratio Tape Diagrams: Given One Amount — Easy Worksheet 2
Grade 6 · Whoobee Name: ____________________ Date: __________
Use the tape diagram. Find the value of one box first, then answer the question.
How to solve
Divide the amount you know by its number of boxes to find the value of one box. Then multiply: the other amount = its number of boxes × the value of one box, and the total = all the boxes × the value of one box. For a ratio of 4 : 5 with 12 cats, 12 ÷ 4 = 3, so there are 5 × 3 = 15 dogs and 9 × 3 = 27 animals.
