Answer 2

Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

a) ratio of 10L to 0.25 L

= 10 L : ( 25/100 ) L

= 10 : ( 1/4 )

= ( 4 × 10 ) : ( 4 × 1/4 )

= 40 : 1

b)2 hours = 120 mins

120 min = 7200 sec

7200 : 45

800:5

160:1

c) Convert into simplest form 13 weeks to 1 year ans: 1:4

There are 52 weeks in 1 year

Therefore, 13 weeks to 52 weeks

1: 4

13 weeks = 13 ×7 days

=91 days

1 year =365 days

then, ratio of 91:365

1 : 4

or.

.

1year = maximum 52 weeks

then 13:52

=1:4

d) 1 century=100 years

1 decade=10 years

so the ratio is 100:10 and in simplest form it is 10:1

(by dividing each number with 10)
