To the nearest​ millimeter, a cell phone is 80 mm long and 42 mm wide. What is the ratio of the width to the​ length?

To find the ratio of the width to the length, we divide the width by the length:

42 mm / 80 mm = 0.525

Therefore, the ratio of the width to the length is 0.525.

explain the steps to get the answer

To find the ratio of width to length, follow these steps:

1. Write down the width and length of the cell phone: Width = 42 mm, Length = 80 mm.
2. Divide the width by the length: 42 mm / 80 mm.
3. Perform the division: 42 / 80 = 0.525.
4. The result 0.525 is the ratio of the width to the length of the cell phone, which can also be expressed as 42:80.

So, the ratio of the width to the length of the cell phone is 0.525 or 42:80.
