Amina’s bed is 190 centimetres in length and 91 centimetres in width. She’s making a one-tenth scale model of her bed. What are the length and width of Amina’s model?

Here’s a sketch of Amina’s bed. The measurements are not accurate. But we know that the length is 190 centimetres and the width is 91. And Amina is making a one-tenth scale model of her bed. So to find the length, we need to calculate 190 centimetres divided by 10. 190 divided by 10 is 19. So the length of Amina’s scale model is 19 centimetres. Now we need to do the same to calculate the width: 91 divided by 10. 91 divided by 10 is 9.1.

So the length of Amina’s one-tenth scale model is 19 centimetres and the width is 9.1 centimetres. To find the answer, we divided the measurements of Amina’s bed by 10.
