How to Write a Ratio

When teaching your students about the concept of a ratio in math class, you probably are sharing with them that this is a way to compare 2 or more things. As an example, if you are looking at the number of students in your class, there may be 16 girls and 12 boys. The ratio of girls to boys would be 16 to 12. This can be represented in 3 different ways. It can be shown as:

• A fraction
• With words
• With a colon

With this worksheet, students will practice writing ratios in different ways. Students will answer 20 questions where ratios are represented with either a colon, with words, or as a fraction. Students must then write the ratio 2 different ways.

Tips for Differentiation + Scaffolding 

In addition to independent student work time, use this worksheet as an activity for:

• Guided math groups 
• Lesson wrap-up
• Fast finishers 
• Homework assignment
• Whole-class review (via smartboard)

If there are students who need a bit of a challenge, encourage them to create an equivalent ratio for each example. This can be represented in any form. 

For students who need a bit of support, consider providing them with a reference sheet or poster showing the 3 different ways a fraction can be represented. Additionally, rather than requiring these students to list 2 alternate forms for each ratio, this can be limited to one.
