Answer:
A. 1/80
Step-by-step explanation:
When multiplying fractions, you first start with the two fractions you want to multiply. You multiply the numerators (the top numbers) together, and then multiply the denominators (the bottom numbers) together. So you do 1x1=1 (numerators), and 10x8=80(denominators). Thus it will be 1/80.
