Step-by-step explanation:

a. sum of ratio= 10

% = 2/10×100

=20%

=12.5%

%=5/16×100

= 31.25%

%=9/16×100

=56.25%

Answer 2

Answer:

sum of ratio part=2+3+5=10

Therefore the percentage of the first part.

2/10 ×100=20./.

second part.

3/10×100=30./.

third part.

5/10×100=50./.

2). 5+8+12=25

5/25×100=20

second part

8/25×100=32

third part

12/25×100=48
