Answer 1

Answer:

a) 1:6

b)2:3

c)84:1

d)4:1

Step-by-step explanation:

a) 18:108=2:12(since 9 is common)

=1:6 (since 2 is common)

b) 40:60 =4:6(since 10 is common)

=2:3(since 2 is common)

c) 2 weeks =2×7 days (as a week = 7 days)

=14

=14×24 hours (as a day =24 hours)

=336 hours

Hence the ratio is 336:4=84:1(as 4 is common)

d) 2L=2×1000 mL=2000 mL

Hence ratio is 2000:500=20:5(as 100 is common)

=4:1
