Explanation:
From the question, we are told that a pet shop sells guinea pigs and goldfish and that the ratio of guinea pigs to goldfish is 20:28.
a) Give this ratio in its simplest form.
The ratio of guinea pigs to goldfish is 20:28. The highest common factor to 20 and 28 is 4. Therefore 20 = 4 × 5 and 28 = 4 × 7. So, the ratio in its simplest form will be 5:7.
b. The shop has a total of 120 guinea pigs and fish. Work out the number of guinea pigs the shop has.
The ratio of guinea pig and goldfish is 5:7. If the shop has a total of 120 guinea pigs and fish, the number of guinea pigs the shop has will be:
= 5/12 × 120
= 5 × 10
= 50 guinea pigs
Answer:
8/mile = 8
Step-by-step explanation:
convert hours to minutes. 3 hours, 28 minutes converted to minutes is...
3*60 (60 minutes in an hour)
=180
180+28 (don't forget to add what was already converted to minutes!)
=208
208/26 (divide time by distance ran)
=8 (8 minutes per mile)
Answer:
0.35 km per minute, 7 km in 20 minutes
Step-by-step explanation:
1 hr = 60 minutes
21 km per 60 minutes = 21/60 = 0.35 km per minute
In 20 minutes: 0.35*20 = 7 km
