2. 1/3+ 1/2+? = 1 So, on the third day, 1/6 was dug.
3.4 kilograms of apples *** 16 are distributed to five students on average, each with (4/5) kilograms and each with (16/5).
4. False score > = 1, true score
5. The first 45 minutes are 20 minutes +25 minutes, 2/5+ 1/2=9/ 10, and the last paragraph is1-9/10 =/kloc-0.
6. For the selected combination of numbers, a multiple of 3 means that the connected combination of numbers is divisible. For example, if you choose three numbers from the topic: 0, 1, 2, 6, you must combine them with 1, 2, 6 or with 0, 1, 2, because: 1+2+6=9 is a multiple of 3, so the maximum multiple should be 6260. Just choose two large numbers, so the number at the end of the maximum multiple of 620 2 is even, so the number at the end can be 2, 0, 6. To satisfy multiples of 2, 3 and 5, the number at the end must be 0, and the first two digits are 1+2=3. So the maximum multiple is 2 10.
7. For this answer, if you have the ability to type, you can work it out yourself. 1-2/3= 1/3 2/3- 1/6=4/6- 1/6=3/6= 1/3 1/5- 1/6= 6/30-5/30= 1/30
8.A+B=34 and A*8+5*B=2 12 For the former formula, B=34-A, and if it is substituted into the latter formula, it is:
A * 8+5 * (34-a) = 212: a =14, then B=20.
9. As mentioned above, to satisfy multiples of 2 and 5 at the same time, the end must be 0, and to satisfy multiples of 3, the decimal+digits must be multiples of 3. Now the unit can only be 0, so the decimal can only be 3, 6, 9. Therefore, the minimum combination is 30.
