Answer:
a) 4 : 1 : 10
b) 25 : 9 : 13
c) 18 : 11 : 3
d) 2000 : 20 : 1
Step-by-step explanation:
We are to put the values in the form a : b : c
a) 40 ml, 1/100 l, 0.1 l
Put them all in ml (1 l = 1000 ml)
40ml, 10 ml, 100 ml
Therefore:
40 : 10 : 100
In lowest terms, 4 : 1 : 10
b) 2 1/2 kg, 900 g, 1.3 kg
Put them all in grams, (1 kg = 1000 g):
2500 g, 900 g, 1300 g
Therefore:
2500 : 900 : 1300
In lowest terms, 25 : 9 : 13
c) 1.5 hrs, 55 minutes, 1/4 hrs
Put them all in minutes (1 hour = 60 minutes)
90 minutes, 55 minutes, 15 minutes
Therefore:
90 : 55 : 15
In lowest terms, 18 : 11 : 3
d) 60 cm, 6 mm, 0.03 cm
Put them all in mm (1 cm = 10 mm)
600 mm, 6 mm, 0.3 mm
Therefore:
600 : 6 : 0.3
In lowest terms, 2000 : 20 : 1 (Divide by 0.3 because a ratio cannot be decimal)
