Two thirds = (10) divided by15 = (18)12 = 27 (18).

2. The Red Star Agricultural Demonstration Base has an experimental land for crops, of which the experimental land for corn accounts for 1 and the experimental station for rice accounts for 2/5 of this land. What kind of crop station has more land?

1= 1/3=5/ 15.

2/5 = 6/ 15.

So rice accounts for a lot.

Young pioneers take part in tree planting activities, and it is just right to divide them into four-person groups and six-person groups. If the total number of young pioneers is between 30 and 40, how many young pioneers are involved in planting trees?

36

4. Turn the following score into the simplest score.

Two thirds = (2/3) 20 of 50 = (2/5) 02 of 65438+26 = (6/13) 08 of 65438+30 = (3/5).

The shop bought a batch of 90 bottles of drinks. If every 6 bottles are packed in a box, can it be filled accurately? What if every 8 bottles are packed in one box?

90/6= 13

90/8= 1 1.25

So every six bottles can be packed in a box, but every eight bottles can't be packed in a box.
