This isn't too tough because the possibilities are few.
The multiples of 7 between 20 and 80 are:
21, 28, 35, 42, 49, 56, 63, 70, and 77.
Of these, when you add 1 ("next year") only one of them becomes a multiple of 5:
49 + 1 = 50
So my age this year is 49. 6 years from now I'll be 55.
52 × 6 = 312 Therefore, 6 years is more than 300 weeks. Note: there are 52 weeks in a year.
That depends on what you are rounding to. 8.6 rounded to the nearest tenth (or less) is 8.6; to the nearest integer is 9; to the nearest multiple of 10 is 10; to the nearest multiple of 100 (or more) is 0.

The Least Common Multiple (LCM) of 30 is 30. The LCM is the smallest multiple that two or more numbers have in common. In the case of 30, it is already the smallest multiple of itself, so the LCM of 30 is 30.
Find a multiple of 110 that is less than (or equal to) the decimal.Find the difference between this multiple and the decimal.Repeat for the next multiple of 110 (which will be 110 more than the previous multiple).Select the multiple of 110 which gives the smaller answer.
Every prime number except 2 must be odd. This is because if it were even it would be divisible by 2 and so wouldn't be a prime number. The next point to note is that all odd numbers are one more or one less than a multiple of 4. Because 2 more than a multiple of 4 is even, and 3 more than a multiple of 4 is the same as 1 less than the multiple of 4 above. Thus every prime number except 2 must be 1 more or 1 less than a multiple of 4.

the next multiple of 3 is 6 more multiples of 3 would be... 9, 12 ,15 ,18, 21, 24, 27, 30, 33 etc..

The same of the past 5000 years. To discover more and more.
