Answer: 3:1
Step-by-step explanation:
Since the jewellery shops sell 240 necklaces in a month and 180 of the necklaces were sold via the shop's website, this means that (240 - 180) = 60 necklaces were sold in a high street shop.
Therefore, the ratio of online sales to shop sales will be:
= 180 / 60
= 3 / 1
= 3:1
Answer:

As this value is definite (has an end), it would be considered rational.
Answer:
8/12
Step-by-step explanation:
First
12 divided by 3 = 4
Second
since 12/3=4 you multiply 3x4 to get 12 so what you do to the denominator you do to the numerator so 2x4=8
Last
so that would give you
2/3 = 8/12
Answer: the cyclist must wait for 25 minutes until the hiker catches up.
Step-by-step explanation:
Distance = speed × time
The Cyclist was travelling in the same direction along the same path
as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is
20 × 5/60 = 100/60 miles
For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.
Time = distance/speed
Time required by hiker to catch up with the cyclist is
(100/60)/4 = 100/240 hour
Converting 100/240 hour to minutes, it becomes
100/240 × 60 = 25 minutes
