Answer 1

Answer:

i) 25 %

ii) 155 %

iii) 12.5 %

iv) 0.8 %

v) 15 %

Step-by-step explanation:

(i) 474 m of 1 km 896 m?

Convert 1 km 896 m:

1 km = 1000 m

1 km 896 m = 1896 m

(474 × 100)/1896 %

= 25%

(ii) 124 of 80?

(124 × 100)/80 %

= 155%

(iii) 4 L 750 mL of 38 L?

Convert 4 L 750 mL:

1 L = 1000 mL

4 L 750 mL = 4750 mL

38 L = 38000 mL

(4750 × 100)/38000 %

= 12.5 %

(iv) 26 m of 3 km 250 m?

Convert 3 km 250 m:

1 km = 1000 m

3 km 250 m = 3250 m

(26 × 100)/3250 %

= 0.8 %

(v) 2127 graduates of 14,180 people?

(2127 × 100)/14180 %

= 15 %

Answer 2

Answer:

(i) 474 m of 1 km 896 m?

$:\Longrightarrow\sf \dfrac{474m}{1km+896m}\times 100\\\\\\:\Longrightarrow\sf \dfrac{474m}{1000m+896m}\times 100\\\\\\:\Longrightarrow\sf \dfrac{474m}{1896m}\times 100\\\\\\:\Longrightarrow\sf \dfrac{1}{4}\times 100\\\\\\:\Longrightarrow\sf 25\%$

$\rule{150}{1}$

(ii) 124 of 80?

$:\Longrightarrow\sf \dfrac{124}{80}\times 100\\\\\\:\Longrightarrow\sf \dfrac{124}{8}\times 10\\\\\\:\Longrightarrow\sf 15.5 \times 10\\\\\\:\Longrightarrow\sf 155\%$

$\rule{150}{1}$

(iii) 4 L 750 mL of 38 L?

$:\Longrightarrow\sf \dfrac{4l + 750ml}{38l}\times 100\\\\\\:\Longrightarrow\sf \dfrac{4000ml + 750ml}{38000ml}\times 100\\\\\\:\Longrightarrow\sf \dfrac{4750ml}{38000ml}\times 100\\\\\\:\Longrightarrow\sf \dfrac{475}{38}\\\\\\:\Longrightarrow\sf 12.5\%$

$\rule{150}{1}$

(iv) 26 m of 3 km 250 m?

$:\Longrightarrow\sf \dfrac{26m}{3km+250m}\times 100\\\\\\:\Longrightarrow\sf \dfrac{26m}{3000m+250m}\times 100\\\\\\:\Longrightarrow\sf \dfrac{26m}{3250m}\times 100\\\\\\:\Longrightarrow\sf 0.8\%$

$\rule{150}{1}$

(v) 2127 graduates of 14,180 people?

$:\Longrightarrow\sf \dfrac{2127}{14180}\times 100\\\\\\:\Longrightarrow\sf \dfrac{212700}{14180}\\\\\\:\Longrightarrow\sf 15\%$
