1 × 4 / 1 + 2 × 7 / 1 + 4 × 7 / 1 + 6 × 10 / 13 / 1 + 8 × 13 / 16 / 1 + 10 × 16 / 19 / 1
1 of 6912 + 1 of 216 + 1 of 432 + 1 of 864 + 1 of 1728 + 1 of 216 + 1 of 3456 + 1 of 6912
The first question should be: 1 + 1 / 4 +

540 out of 1.19
1 out of 2.72

1. The team has built 2400 meters of roads this year, one fifth less than last year. How many meters of roads were built last year?
2. The school library purchased 60 science and technology books, which is 1 / 5 less than the story books?

Road construction last year: 2400 ÷ (1-1 / 5) = 3000m
Purchase story books: 60 ÷ (1-1 / 5) = 75

Elementary school mathematics score calculation problem

2010×﹙2010/2011﹚
＝﹙2011－1﹚×﹙2010/2011﹚
＝2011×﹙2010/2011﹚－﹙2010/2011﹚
＝2010－﹙2010/2011﹚
= 2010 out of 2009 and 2011 (with scores)
