4. Example: 0.53 x 2.618 2.618 has more digits (4) than 0.53 (3), so it goes on top. 2. 618 0. 53x 4 2 58 1 7 00 4 90 3 13 000000+ 457 1 831 Decimal Places three two five.

5. Example: 2.7 x 3.5

6. Let’s try a few together.

7. 7.56 x 3.8 = 287.28 2872.8 28.728

8. .3445 x 3.9 = 1.34355 13.4355 134.355

9. 13.723 x 122.5 = 16.810675 168.10675 1681.0675

10. .55 x.007 = 38.5.00385.0385

11. You’re correct!

12. Incorrect, try again Remember to count the digits behind the decimal points in the problem. You must have this many digits behind the decimal point in the answer.
