Answer» (i) 3.9 x 10 = 39 3.9 x 100 = 390.0 = 390 3.9 x 1000 = 3900.0 =3900 (ii) 2.89 x 10 = 28.9 2.89 x 100 = 289 2.89 x 1000 = 2890.00 = 2890 (iii) 0.0829 x 10 = 0.829 0.0829 x 100 = 8.29 0.0829 x 1000 = 82.9 (iv) 40.3 x 10 = 403 40.3 x 100 = 4030 40.3 x 1000 = 40300 (v) 0.3725 x 10 = 3.725 0.3725 x 100 = 37.25 0.3725 x 1000 = 372.5

Multiply each of the following numbers by 10, 100 and 1000 :(i) 3.9(ii) 2.89(iii) 0.0829(iv) 40.3(v) 0.3725

Answer»

(i) 3.9 x 10 = 39

3.9 x 100 = 390.0 = 390

3.9 x 1000 = 3900.0 =3900

(ii) 2.89 x 10 = 28.9

2.89 x 100 = 289

2.89 x 1000 = 2890.00 = 2890

(iii) 0.0829 x 10 = 0.829

0.0829 x 100 = 8.29

0.0829 x 1000 = 82.9

(iv) 40.3 x 10 = 403

40.3 x 100 = 4030

40.3 x 1000 = 40300

(v) 0.3725 x 10 = 3.725

0.3725 x 100 = 37.25

0.3725 x 1000 = 372.5
