1/3 of 18 is a number where 2 is less than 2/3. What's this number?
( 18* 1/3+2)/(2/3)= 12
2
How much is 15 less than its 4/5?
15*(4/5- 1/5)=9
three

What percentage of the annual plan can be completed? What's the ratio of overfulfilling the plan in the whole year?
The first half =7/24*2=7/ 12
Annual excess = 7/12 * 2-1=1/6
