LC: To solve problems in length using x or ÷.

 

 

What do I know?

 

2m per shirt

23 shirts

 

23 x 2 

 

23 x 2 = 46m 

What do I know?

 

5 times longer

98 cm

 

98 x 5 = 490cm

 

            98

         x   5

90 x 5   450

 8 x 5     40

           490

What do I know?

 

75cm

3 times as long

 

75 x 3 = 225cm This is the length of Emma's ribbon.

 

                75

             x   3

70 x 3       210

  5 x 3        15

              225

 

Amirah's ribbon + Emma's ribbon

225 + 75 = 300

 

So the total length of all the ribbon is 300cm
