Question

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?

Answer 1

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

Step-by-step explanation:

According to given statement;

Length of individual stringing beads = 0.19 inches

Rounding off = 0.2 inches

Length of row of 9 beads = 9* rounded off length of individual beads

Length of row of 9 beads = 9*0.2

Length of row of 9 beads = 1.80 inches

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