Sav [38]
C:t=2:3
t:h=2:1

multiply first equation by 2 and 2nd by 3
c:t=4:6
t:h=6:3

c:t:h=4:6:3

if t is 4 more than c
t is 6 units and c is 4
6-4=2
so 4=2 units
2=1 unit

At a kennel, the ratio of dogs to cats was 4to9. if there were 64 dog s how many cats were there
hichkok12 [17]
Dogs. Cats.
4. To. 9

64. To. ?

I solved this by guess-timating, and i got it right. I know that 8*8=64 and 4*2=8 8*2=16, and i checked and got 16*4=64.
Since you do:

Dogs:4 * 16= 64
You have to do:
Cats:9 * 16= # of cats
And 9*16=144,

So there are 144 cats at the kennel
