Question

find the ratio of the following
plz it's important​

Answer 1

Answer:

SOLUTION:

i) 30minutes to 1.5 hours, therefore we have to convert 1.5hours into minutes

required ratio =\frac{30}{90}=\frac{30\div30}{90\div30}=\frac{1}{3}=1:3

[HCF of 30 and 90 =30]

ii) 40cm to 1.5m, therefore we have to convert

1.5m to cm , m=100cm therefore, 1.5m=1.5X100cm = 150cm

therefore, required ratio =\frac{40}{150}=\frac{40\div10}{150\div10}=\frac{4}{15}=4:15

[HCF of 40cm and 150cm is 10]

iii) 55paise to1rupee

therefore, we need to convert 1rupee into paise

1rs=100paise

require ratio=\frac{55}{100}=\frac{55\div5}{100\div5}=\frac{11}{20}=11:20

[HCF of 55 and 100 =5]

iv) 500ml to 2litres

therefore, we need to convert litres to ml

1l=1000ml = 2X1000ml

required ratio= \frac{500\div100}{2000\div100}=\frac{5}{20}=5:20

[HCF of 500, 2000 is 100]
