A runner plans to run 4 miles (original number: 4). She considers two plans:

• Plan A: $4 \times \frac{9}{8}$ miles • Plan B: $4 \times \frac{3}{8}$ miles

Which statement correctly explains why one plan gives a distance greater than 4 and the other gives a distance less than 4? (Products: $4\times\frac{9}{8}$ and $4\times\frac{3}{8}$.)

A rope is 10 meters long (original number: 10). You see two expressions:

• $10 \times \frac{11}{10}$ • $10 \times \frac{7}{10}$

Which statement correctly compares the products to the original number 10? (Products: $10\times\frac{11}{10}$ and $10\times\frac{7}{10}$.)
