Question

9 apes weigh as much as 4 bears, 8 bears weigh as much as 15 cougars, 10 cougars weigh as much as 27 deer how many deer weigh the same as 4 apes.​

Answer 1

Answer:

9 deers

Step-by-step explanation:

9 apes = 4 bears

therefore 4 apes weigh

$4 \times \frac{4}{9} \: bears = \frac{16}{9} \: bears$

8 bears = 15 cougars

therefore 16/9 bears weigh

$\frac{15 \times 2}{9} \: cougars = \frac{30}{9} cougars$

10 cougars = 27 deer

therefore 30/9 cougars

$\frac{27 \times 3}{9} \: deers = 9 \: deers$

Answer 2

given, weight of

9 apes = 4 bears

8 bears = 15 cougars

10 cougars = 27 deer

to find 4 apes = how many deer

here I would prefer unitary method to ratio method to solve this

9 apes = 4 bears

1 ape = 4/9 bears

4 apes = 16/9 bears

again,

8 bears = 15 cougars

1 bear = 15/8 cougar

16/9 bears = (15/8)*(16/9) cougar

= 10/3 cougar

10 cougars = 27 deer

1 cougar = 27/10 deer

10/3 cougar = (27/10)*(10/3)

= 9 deer

thus,

4 apes = 9 deer
