Question

if a:b= 5:6 & b:c= 2.8:3.5 find a:c

Answer 1

Answer:

2:3

Step-by-step explanation:

a:b  =   5 : 6

  b:c=        2.8 : 3.5

here we should make the b value equal

so as to do that we need to multiply a:b that is 5:6 with 2.8 and b:c that is 2.8:3.5 with 6

we get a:b:b:c=14:16.8:16.8:21

here b is same in both the ratios so take it directli a:cis 14 :21

by simplifying 2:3
