The students of class 61 went to plant trees. The whole class was divided into three groups, 16 in the first group, 14 in the second group, and 18 in the third group. The 96 saplings were divided into three groups according to the number of people, each group How many saplings are there?

The students of class 61 went to plant trees. The whole class was divided into three groups, 16 in the first group, 14 in the second group, and 18 in the third group. The 96 saplings were divided into three groups according to the number of people, each group How many saplings are there?

A group of 32 16 * 2 trees
Group 2: 28 trees, 14 * 2
Three groups of 36 trees, 18 * 2

Class four (1) plants trees. If everyone plants 2 trees, there will be 18 more trees. If everyone plants 3 trees, there will be 18 less trees. How many people plant trees and how many trees need to be planted?
Want an equation

(18 + 18) / (3-2) = 36 (person)
36 × 2 + 18 = 90 (trees)

3 / 8 * [(1 / 2 + 2 / 3) / 5 / 6-2 / 3]

Original form
=3/8*[(3/2+8/3)/(5/6)-7/3]
=3/8*(3/2*6/5+8/3*6/5-7/3)
=3/8*(9/5+16/5-7/3)
=3/8(25/5-7/3)
=3/8(5-7/3)
=3/8(15/3-7/3)
=3/8*8/3
=1

3 / 5 - (5 / 8-1 / 6)

3/5-(5/8-1/6)
=3/5-(15/24-4/24)
=3/5-11/24
=72/120-55/120
=17/120

4.6 × 1 and 3 / 8 + 8.4 △ 8 / 11-1 and 3 / 8 × 5
It should be simple, online and so on

=（23/5）*（11/8）+（42/5）*（11/8）-（11/8）*（25/5）
=（（23+42-25）/5）*（11/8）
=（40/5）*（11/8）
=11

1 / 3-4 / 1 =?, 1 / 2 + 5 / 1 =?, 1 / 6-7 / 1 =?, 1 / 5 + 6 / 1 =?, 1 / 7-8 / 1 =
1 / 8 + 1 / 9 =? 1 / 2-1 / 3 =? 1 out of 9 + 1 out of 10

1/3-1/4=1/12
1/2+1/5=7/10
1/6-1/7=1/42
1/5+1/6=11/30
1/7-1/8=1/56
1/8+1/9=17/72
1/2-1/3=1/6
1/9+1/10=19/90

8.75 △ [1 / 2 × (3 / 4-1 / 3)]

Original formula = 8.75 △ [1 / 2 × 5 / 12]

[5 1 / 2 × (Δ + 2 3 / 14) △ 1 4 / 7] / (14-8 1 / 4-4.75) = 13

Title: [5 1 / 2 × (Δ + 2 3 / 14) △ 1 4 / 7] / (14-8 1 / 4-4.75) = 13
Find the value of
answer:
(5.5 * (△ 2 + 3 / 14) / 1 + 4 / 7) / (14-8 + 1 / 4-4.75) = 13
(5.5 * (△ 2 + 3 / 14) / (1 + 4 / 7) / (14-13) = 13
(5.5 * (△ 2 + 3 / 14) / (1 + 4 / 7) = 13
Then 5.5 * (△ + 2 and 3 / 14) = 13 * 7 / 11
5 * (△ 2 + 3 / 14) = 91 / 11
Then △ + 31 / 14 = 182 / 61
△=182/61—31/14
△=657/854

75 - [(- 3 / 8) + (- 1 / 2) - (- 5 / 6) + 4 and 2 / 3] - 0.125
To write the process, thank you,

2363259763 ,
3.75 - [(- 3 / 8) + (- 1 / 2) - (- 5 / 6) + 4 and 2 / 3] - 0.125
75 + 0.375 + 0.5-5 / 6-4 and 2 / 3-0.125 respectively
= (3.75 + 0.375 + 0.5-0.125) - (5 / 6 + 4 and 2 / 3)
＝4.5－5.5
＝－1
