Answer 1

Step-by-step explanation:

i)

Rs. 1.80 = $1.80 \times 100 = 180$ paise.

therefore,

$\frac{27p}{180p} \times 100 = 15 \%$

ii)

1.5m = $1.5 \times 100 = 150m$

therefore,

$\frac{48cm}{150cm} \times 100 = 32 \%$

iii)

2.5kg = $2.5 \times 1000 = 2500g$

therefore,

$\frac{175g}{2500g} \times 100 = 7\%$

iv)

2min = $2 \times 60 = 120s$

2min 24 s = 120+24 = 144s

1hour = $1 \times 60 \times 60 = 3600s$

therefore,

$\frac{144s}{3600s} \times 100 = 4\%$

v)

1.05km = 1.05 × 1000 = 1050 m

therefore,

$\frac{189m}{1050m} \times 100 = 18\%$
