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
