Q57) if 1/4 of a packet cover 1/5 then using a packet is using 4* 1/4 of it. This means that 4*1/5 of the garden would be covered which = 4/5.
q58) the total is 24 and 9 of them are boys. Therefore it follows that 9/24 of them are boys and so thats the probability of choosing a boy at random.
Plug in the values
3(5) - 5(1)
15 - 5 = 10
Solution: 10
Answer:
r = - 3
Step-by-step explanation:
To find the common ratio r, divide consecutive terms
- 9 ÷ 3 = - 3
27 ÷ - 9 = - 3
- 81 ÷ 27 = - 3
Thus common ratio = - 3
