Answer:
91.
Step-by-step explanation:
The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.
2*3*5 = 30 but 31 is not a multiple of 7.
2*2*3*5 = 60 but 61 is not divisible by 7.
2*3*3*5 = 90 and 91 is divisible by 7.

one ten was traded for ten ones
Step-by-step explanation:

370 +2 = 360 +12 . . . . where the "+" numbers are the numbers of ones
