Answer 1

Answer:

a) fraction = 90min/ 130min

simplest form = 9/13

b) fraction = 200m / 1400m

simplest form = 1/7

Answer 2

Answer:

= 30 : 15

First we need to convert the given ratio into fraction,

= 30/15, [divide both the numerator and denominator by 15 since, the h.c.f. of 30 and 15 is 15]

= 2/1

= 2 : 1

(ii) 60 and 48

= 60 : 48

First we need to convert the given ratio into fraction,

= 60/48 (divide both the numerator and denominator by 12 since, the h.c.f. of 60 and 48 is 12)

= 5/4

= 5 : 4
