Therefore, Fu Ming produced a total of 1- 1/4-2/5=7/20.
Total number of parts is 2 10÷7/20=600.
Zhang Wei produced 600* 1/4= 150.
Method 2: Li Li said, "The number of parts I produce is two-thirds of the sum of Zhang Wei and Fu Ming." Ber Ber produced 2/(3+2)= 2/5 of the total.
Therefore, Fu Ming produced a total of 1- 1/4-2/5=7/20.
The ratio of numbers generated by Zhang Wei and Fu Ming is 1/4: 7/20 = 5: 7.
Zhang Wei produced 2 10/3*5= 150.
