@Janhavi.
Multiplying with 1/10 means dividing 2994 by 10 which gives 299.4 without altering the rules.

29.94/1.45 = ((2994x10^(-2)/(14.5 * 10^(-1)).
29.94/1.45 = (2994x14.5)x10^(-1),
29.94/1.45 = 172x10^(-1),
29.94/1.45 = 17.2.
29.94/1.45 = (2994x14.5)x10^(-1),
29.94/1.45 = 172x10^(-1),
29.94/1.45 = 17.2.

14.5=172
1.45 = ?.
So, 1.45 * 172/14.5=17.2.
1.45 = ?.
So, 1.45 * 172/14.5=17.2.

29.94/1.45 * 100/10 * 10/100,
100/10 * 10/100 = 1,
2994/14.5 = 172 given,
172 * 10/100,
17.2.
100/10 * 10/100 = 1,
2994/14.5 = 172 given,
172 * 10/100,
17.2.

29.94/1.45*10/10.
=299.4/14.5.
299.4/14.5*10/10.
=299.4*10/14.5*1/10.
2994/14.5*1/10.
But 2994/14.5=172.
So,
172*1/10,
=172/10,
=17.2.
=299.4/14.5.
299.4/14.5*10/10.
=299.4*10/14.5*1/10.
2994/14.5*1/10.
But 2994/14.5=172.
So,
172*1/10,
=172/10,
=17.2.

2994/14.5 * 10/100 = 172* 10/100 (multiply by 10/100 on both sides).
29.94/1.45 = 172*10/100.
29.94/1.45 = 172*1/10.
29.94/1.45 = 17.2.
29.94/1.45 = 172*10/100.
29.94/1.45 = 172*1/10.
29.94/1.45 = 17.2.

2994/14.5 = 172 ( given).
29.94/1.45 = ?.
Now
29.94/1.45 *100/10 = 2994/14.5.
29.94/1.45* 100/10 = 172,
29.94/1.45 = 172 * 10/100,
29.94/1.45 = 17.2.
29.94/1.45 = ?.
Now
29.94/1.45 *100/10 = 2994/14.5.
29.94/1.45* 100/10 = 172,
29.94/1.45 = 172 * 10/100,
29.94/1.45 = 17.2.

Given.
2994/14.5 = 172,
Now 29.94/1.45 can be expressed as 2994*10/14.5*100 = >2994/14.5*10.
Since 2994/14.5 = 172 then,
172 * 1/10 = 17.2.
2994/14.5 = 172,
Now 29.94/1.45 can be expressed as 2994*10/14.5*100 = >2994/14.5*10.
Since 2994/14.5 = 172 then,
172 * 1/10 = 17.2.
