Question

The ratio of red beads to white beads

on a necklace is 2:1.
What fraction of the beads are white?

Answer 1

Explanation:

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 2 + 1 = 3

Part A = 2 and Part B = 1 are numerators for each fraction.

The fractions are then:

2/3 and 1/3

Meaning:

Part A is 2/3 of the whole

Part B is 1/3 of the whole
