Answer:

1.) 11/50

2.) 4343/10000

3.)

4.)

5.) 101/625

Step-by-step explanation:

1.) 0.22/1 * 100/100 = 22/100

22÷2/100÷2 = 11/50

2.) 0.4343 = 0.4343/1

0.4343/1 * 10000/10000 = 4343/10000

0.4343 = 4343/10000

3.) 2.15 = 2.15/1

2.15/1 * 100/100 = 215/100

215÷5/100÷5 = 43/20

= 2 3/20

4.) 1.543 = 1.543/1

1.543/1 * 1000/1000 = 1543/1000

= 1 543/1000

5.) 0.1616 = 0.1616/1

0.1616/1 * 10000/10000 = 1616/10000

1616÷16/10000÷16 = 101/625
