To multiply fractions, you simply multiply the numerators (top numbers) together and the denominators (bottom numbers) together.
For 1.2 • 0.4, we can convert the decimals to fractions:
1.2 = 1 2/10 = 6/5
0.4 = 4/10 = 2/5
Now we can multiply the fractions:
(6/5) • (2/5) = 12/25
So, the product of 1.2 and 0.4 is 12/25.
