Are four tenths bigger than one third?

Answer 1

Yes.

To compare fractions, convert to equivalent fractions with the same denominator (bottom number), then the numerators (top numbers) can be directly compared:

4/10 = (4×3)/(10×3) = 12/30

1/3 = (1×10)/(3×10) = 10/30

12 > 10

→ 12/30 > 10/30

→ 4/10 > 1/3
