b) In how many jumps will the squirrel reach 27?
27 Ã· 3 =
c) Which number will the kangaroo reach in two jumps?
d) Who all will meet at the number 15?
e) Will the rabbit ever be at the number 18?
f) How many jumps of the rabbit equal one jump of the horse?
g) How many jumps of the horse equals two jumps of the kangaroo?
h) Which is the smallest number where the frog and the squirrel will meet?

Answer: a) Since the frog jumps 2 steps at a time, to find the number of jumps taken to reach 30, divide 30 by 2.
30 Ã· 2 = 15
Therefore, the frog will reach 30 in 15 jumps.
b) Since the squirrel jumps 3 steps at a time, to find the number of jumps taken to reach 27, divide 27 by 3.
27 Ã· 3 = 9
Therefore, the squirrel will take 9 jumps to reach 27.
c) Since the kangaroo jumps 30 steps at a time, to find the number of steps in 2 jumps, multiply 30 by 2.
30 Ã— 2 = 60
Therefore, the kangaroo will reach 60 in two jumps.
d) Jumps of the squirrel are:
3, 6, 9, 12, 15, 18, 21 â€¦.
Jumps of the rabbit are:
5, 10, 15, 20, 25, 30, 35 â€¦.
Jumps of the horse are:
15, 30, 45, 60â€¦
Hence, the squirrel, the horse, and the rabbit will meet at 15.
e) Jumps of the rabbit are:
5, 10, 15, 20, 25, 30, 35 â€¦.
Therefore, the rabbit will never reach 18.
f) A horse jumps 15 steps at a time and a rabbit jumps 5 steps at a time. So, the rabbit will be at 15 in
15 Ã· 5 = 3 jumps
Hence, the rabbitâ€™s three jumps are equal to one jump of the horse.
g) A horse jumps 15 steps at a time and a kangaroo jumps 30 steps at a time.
Two jumps of the kangaroo
30 Ã— 2 = 60
So, to reach 60 the horse will have to jump
60 Ã· 15 = 4 jumps
Hence, the horseâ€™s four jumps are equal to two jumps of the kangaroo.
h) Jumps of the frog are:
2, 4, 6, 8, â€¦.
Jumps of the squirrel are:
3, 6, 9, 12, â€¦.
The frog will meet with the squirrel at 6, which is the smallest number where they meet.
