  5. i'm bored so i'll be solving these. :] a. 1:3 b. 3:1 c. 3/4 d. 1/4 ----- a. £15, £35 b. £9, £6 c. £160, £80 d. £70, £20 ----- a. 0.5m b. 1200cm ----- a.1:100 b.1:200 c.1:50 ----- i'm quite sure about my answers :]
  6. well.... 1. (ratios are easy, if they want dogs to cats, just put the number of dogs in front of the number of cats, you can also put them into fractions) a.2:6 (2/6, or 1/3) I do believe that you can reduce the ratios b.6:2 (6/2, or 3) c.This one, if I remember, you have to take the # of cats, 6, and put that over the total amount of pets, or 8, so that would be (6/8), or (3/4) d. (2/8) or (1/4) sorry, I can't figure out the rest, is there any more info for them?
  7. 1. a. 1 dog : 3 cats b. 3 cats : 1 dog c. 4 animals : 3 cats d. 4 animals :1 dog 2. a. 15 : 35 b. 9 : 6 c. 160 : 80 d. 70 : 20 3. 500m : 500000 scale x/.12=1/1000 x.12 x.12 x=.00012m 4. I'm confused
  8. 1 (a) 1:3 (b) 3:1 (c) 3/4 (d) 1/4 2 (a) 3+7 = 10 thus 3:7 => 15:35 (b) 9:6 (c) 160:80 (d) 70:20 3 (a) 50cm (b) 12m 4 (a) 1:100 (b) 1:200 (c) 1:50
