Answer 1

Hi ,

************************************
we know that ,

if a: b : : c : d then ad = bc

************************************

a ) 2 : 9 : : 64 : x

2 × x = 9 × 64

x = ( 9 × 64 ) / 2

x = 9 × 32

x = 288

b ) 18 : 48 : : 180 : y

18 × y = 48 × 180

y = ( 48 × 180 ) / 18

y = 48 × 10

y = 480

I hope this helps you.
