Answer:
180 houses
Step-by-step explanation:
The 3 part of the ratio 10 : 3 represents 30 bungalows, thus
30 ÷ 3 = 10 ← value of 1 part of the ratio
10 parts = 10 × 10 = 100 ← number of flats
The 5 part of the ratio 9 : 5 represents 100 flats, thus
100 ÷ 5 = 20 ← value of 1 part of the ratio, then
9 parts = 9 × 20 = 180 ← number of houses
Answer:
C
Step-by-step explanation:
Keep a consistent ratio of 4:2, and we need a total of 36 glasses of punch.
So if the ratio 4:2 is a total of 6, then we would need 6 times the amount because 6*6 is 36. So 4 and 2 * 6 or 6 (4+2) = 24+12. So the answer is C.
Hope this helps in some way.
