2 / 3-1 / 8 - (- 1 / 3) + (- 3 / 8)

2 / 3-1 / 8 - (- 1 / 3) + (- 3 / 8)

2 / 3-8 / 1 - (- 1 / 3) + (- 3 / 8) = 2 / 3-1 / 8 + 1 / 3-3 / 8 = 1-4 / 8 = 1 / 2 understand, please adopt it in time!

How about 152 × 3 / 8?

152÷8＝19
19 × 3 = 57!

3 / 4 plus 7 / 9 plus 1 / 4 minus 4 / 9

3 / 4 plus 7 / 9 plus 1 / 4 minus 4 / 9
=(3 / 4 + 1 / 4) + (7 / 9-4 / 9)
=1 + 3 / 9
=1 and 3 / 9

3 / 4 of a number is 2 more than 7. What is 2 / 3 of this number

Pro, check the title, the description is not clear

5 / 6 of a number is more than 2 / 3 of it. 7 what is the number?

7÷(5/6-2/3)=42,

4 / 7 of a number is 3 more than 1 / 4 of 20. What's the number?

(20*1/4+3)/(4/7)=14

3 / 4 of a number is 3 / 7. What's the number?

This number = 3 / 7 △ 3 / 4 = 4 / 7

The sum of 1 / 3 of a number and 6 / 7 of this number is 44 more than this number?
There are 702 students in a certain school. There are 18 less girls than 4 / 5 boys. How many boys and girls are there?
The two barrels of a and B contain a total of 44 kg. If 1 / 5 of a is poured out and 2.8 kg is poured in by B, then the two barrels of oil are equal. How many kg are each?

The sum of 1 / 3 of a number and 6 / 7 of this number is 44 more than this number?
44÷(1/3+6/7-1)
=44÷4/21
=231
Equation:
Let this number be X
1/3X+6/7X-X=44
(1/3+6/7-1/)X=44
4/21X=44
X=231
There are 702 students in a certain school. There are 18 less girls than 4 / 5 boys. How many boys and girls are there?
Formula: male: (702 + 18) / (1 + 4 / 5) = 400
Female: 702-400 = 302
Equation:
Suppose there are x boys, then there are (702-x) girls
4/5X-18=702-X
4/5X+X=702+18
9/5X=720
X=400
So, there are 702-400 girls = 302
The two barrels of a and B contain a total of 44 kg. If 1 / 5 of a is poured out and 2.8 kg is poured in by B, then the two barrels of oil are equal. How many kg are each?
Formula: a barrel: (44 + 2.8) / (1 + 1-1 / 5) = 26kg
B barrel: 44-26 = 18kg
Equation:
Let a barrel have x kg, then B barrel has (44-x) kg
(1-1/5)X=44-X+2.8
4/5X+X=46.8
9/5X=46.8
X=26
So, B barrel: 44-26 = 18 kg

One third more than a number is 12. What is this number?

9

One third of a number is 28% larger than 25%. How much is this number
Why are there so many illiterates,

Let this number be X
The equation is' x / 3 = 25% x + 28 '
x=336
