Answer:
16 sweets
Step-by-step explanation:
Adam : Rob : Clare
4 : 5 : 8
Find the difference in units of Rob and Claire.
8 - 5 = 3 units
3 units = 12
1 unit = 12 ÷ 3 = 4
4 units = 4 x 4 = 16
49.65-50.35
0.7% of 50 is 0.35. We can find the range by first subtracting that from 50 which is 49.65, then adding it to get 50.35.
81
Hence answer is 81.
