Keep change flip////// times 4 by 15 and add 3 and your answer would be over 4 and then times 7 by 7 and add 5 and then you keep your first answer change your dividing sign to a multiplication sign and flip your answer (switch top with bottom and bottom with top) and then multiply across and simplify if needed

In jungle one year monkey population increased in a ratio of 8:7 but the next year it is decreased in the ratio of 16:17.Tell ho

AleksAgata [21]

Answer:

Population of monkeys after 2 years = 3200

Step-by-step explanation:

Total number of monkeys at the start = 2975

Increase ratio of monkey population one year = $8:7$

∴ New population of monkeys after 1 year= $Total\ population \times Increase\ ratio = 2975\times \frac{8}{7} =3400$

Decrease ratio the next year = $16:17$

∴ Population of monkeys after 2 years= $New\ population \times Decrease\ ratio = 3400\times \frac{16}{17} =3200$

Jacky baked some biscuits.he kept 3/7 of the biscuits in container A.5/8 of the remainder in container B and rest in container C

Colt1911 [192]

Let "b" represent the number of biscuits Jacky baked.
.. container A holds (3/7)b
.. container B holds (1 -3/7)*(5/8)b = (5/14)b
.. container C holds (1 -3/7 -5/14)b = (3/14)b = 168

Then
.. b = 168/(3/14) = 784

Jacky baked 784 biscuits.
