Ratio Bead Strings

Learners arrange beads for class-club colours.

Describe and compare quantities using ratios.

A class club makes bead strings in house colours, and learners must keep the colour mix the same for every string.

Ratio Bead Strings illustration

Learners arrange beads for class-club colours.

A string has red to blue beads in the ratio 3:2. How many blue beads go with 12 red beads?

  1. Scale the red part from 3 to 12 by multiplying by 4.
  2. Multiply the blue part by the same 4, so 2 x 4 = 8 blue beads.
