Answer 1

Answer:

Step by step explanation:

(a) 25% = 25×1/100 = 25/100

= 1/4 = 1:4

(b) 10% = 10×1/100 = 10/100

= 1/10 = 1:10

(c)

$62 \times \frac{1}{2}\%$

$\frac{125}{2} \%$

$\frac{125}{2} \times \frac{1}{100}$

$\frac{125}{200}$

$\frac{5}{8}$ = 5:8

(d)

$2 \times \frac{1}{2} \%$

$\frac{5}{2} \%$

$\frac{5}{2} \times \frac{1}{100}$

$\frac{5}{200}$

$\frac{1}{40}$ = 1:40

(e) 5.5%

= 5.5×1/100

= 5.5 /100

= 55/1000

= 11/ 200

= 11:200
