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
