Rama is stringing beads whose lengths are each 0.19 inches. How can rounding be used to estimate the length of a row of

9 beads?

1. Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 + 0.20 = 9.20 inches.

2. Since the beads are about 0.10 inches, the length of a row of 9 beads will be approximately 9 + 0.10 = 9.10 inches

3. Since the beads are about 0.10 inches, the length of a row of 9 beads will be approximately 9 x 0.10 = 0.80 inches.

4. Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 x 0.20 = 1.80 inches.
