Answer 1

Step-by-step explanation:

1.

a) 2.5kg: 350g

= 2.5kg/350g

=2.5×1000g/350g

= 2500/350

=50/7

50:7

b) 15/27:9/7

= 15/27/9/7

=15/27 × 7/9

= 5/9×7/9

= 35/81

35:81

c) 1.2:33/10:6.5

= 1.2×10 :33 : 6.5×10

10

12:33:65

2.

a:b:c= 80:120:144

a) 80:120:144 ( 8 can divide all of em)

= 10:15:18

b) b:a = 15:10 ( 5 can divide both)

= 3:2

c) b:c= 15:18 ( 3 can divide both)

= 5:6
