Multiply 4/5 × 5/8 write the answer in simplest form.

To multiply fractions, you simply multiply the numerators (top numbers) together and the denominators (bottom numbers) together.

So, multiplying 4/5 and 5/8 would give us:
(4 × 5) / (5 × 8) = 20/40

However, we can simplify this fraction further. Both 20 and 40 can be divided by 20, so we divide them both by 20 to get:
20/40 = 1/2

Therefore, 4/5 × 5/8 = 1/2 in simplest form.
