1 There are red, blue and yellow ribbons. The red
ribbon is - meters long. the blue ribbon is
1
3
meters long, and the yellow ribbon is meters
8
long. About how many times longer is the blue
ribbon than the red ribbon?

3 times longer

Step-by-step explanation:

[] With your comment of the following, we can answer this question;

"There are red blue and yellow ribbons. The red ribbon is 1/2 meters long the blue ribbon is 1 1/2 meters long, and the yellow ribbon Is 3/8 meters long. About how many times longer is the blue ribbon than the red ribbon?"

-> The problem is only asking about blue (1 1/2) and red (1/2) so we can ignore yellow in this case.

[] It is asking how many times longer the blue ribbon is. Times is multiplication, and the opposite of multiplication is division.

-> 1 1/2 can become 3/2 to make doing division easier

-> 3/2 / 1/2 becomes 3/2 * 2/1, and then we multiply across

-> The blue ribbon is 3 times longer than the red ribbon.

Have a nice day!
