Sneaky bit of ratio homework help!
With ratios add both sides together and you have the number of parts:
It's a ratio of 2:1
2 + 1 = 3 parts.
Divide the total into 3 parts: 135/3 = 45
Each part is 45cm.
The two sections of tape are 90 cm and 45 cm.
If you remember to divide it into parts, it's easy.
