Question

Alexis is knitting a blanket 2 meters long. Every 2 decimeters, she changes the color of the yarn to make stripes. How many stripes will the blanket have?

Answer 1

There are 10 stripes in the blanket.

Explanation:

We are given the following in the question:

Length of blanket = 2 meters

1 meter = 10 decimeter

Length of blanket in decimeter =

`2* 10 = 20\text{ decimeters}`

Change of color = Every 2 decimeters.

Number of stripe =

`=\frac{\text{Length of blanket}}{\text{Length of change of color of stripe}}\\\\=(20)/(2) = 10`

Thus, there are 10 stripes in the blanket.
