Answer:
11.
1.68 × n = 0.672
1.68n = 0.672
1.68n ÷ 1.68 = 0.672 ÷ 1.68
12.
n × 0.001 = 0.00207
0.001n = 0.00207
0.001n ÷ 0.001 = 0.00207 ÷ 0.001
13.
3.28 × 0.0001 = n
14.
n × 4.2 = 4.914
4.2n = 4.914
4.2n ÷ 4.2 = 4.914 ÷ 4.2
15.
335 × n = 23.45
335n = 23.45
335n ÷ 335 = 23.45 ÷ 335

1.68 × n = 0.672
1.68n = 0.672
1.68n ÷ 1.68 = 0.672 ÷ 1.68
n = 0.4
12.
n × 0.001 = 0.00207
0.001n = 0.00207
0.001n ÷ 0.001 = 0.00207 ÷ 0.001
n = 2.07
13.
3.28 × 0.0001 = n
0.000328 or 3.28×10^-4 = n
14.
n × 4.2 = 4.914
4.2n = 4.914
4.2n ÷ 4.2 = 4.914 ÷ 4.2
n = 1.17
15.
335 × n = 23.45
335n = 23.45
335n ÷ 335 = 23.45 ÷ 335
n = 0.07
