penjelasan:

1.0,5=5/10

25%=25/100:25/25= 1/4

3 1/4=13/4

=5/10×1/4=5/40:5/5=1/8

=1/8:13/4=1/8×4/13=4/104:4/4=1/26

2.3 1/5=16/5

15%=15/100:5/5=3/20

0,35=35/100:5/5=7/2

= 16/5:3/20=16/5×20/3=320/15:5/5=64/3

=64/3×7/2=448/6:2/2=224/3= 74 2/3

3.4 1/2=9/2

25%=25/100:25/25=1/4

0,5=5/10

=9/2:1/4=9/2×4/1=36/2

=36/2×5/10=180/20:20/20=9/1= 9

4.25%=25/100:25/25=1/4

2 1/2=5/2

0,4=4/10

=1/4×5/2=5/8

=5/8:4/10=5/8×10/4=50/32:2/2=25/16=1 9/16

5.3 1/4=13/4

0,25=25/100:25/25=1/4

5%=5/100:5/5=1/20

=13/4:1/4=13/4×4/1=52/4:4/4=13/1
