Answer:
283 or 382
Step-by-step explanation:
The number of children in 1st grade has 3 digits.The digit in the number are 2,3,and 8 .
Since the digit 8 means 80 in the number. The other two numbers could interchange the Hundred and Unit position respectively.
The possible numbers are:
I. 200+80+3=283
II. 300+80+2=382
The possible number of children in 1st Grade is either 283 or 382.
25% is the answer cause there are 4 part 100% of 4 is 25% for each

Let's the length to be x,
then the width is 8x - 2.
Perimeter of a rectangle = 2*Width + 2*Length
Perimeter of the rectangle = 2(8x-2) + 2x = 16x - 4 + 2x = 18x - 4
Ar the same time, Perimeter of the rectangle = 88.
So, we can write
18x - 4 = 88
18x = 84
9x=42
x= 42/9 cm (length) or ≈ 4.67 cm (length)
8x - 2 = 8*42/9 - 2 ≈ 35.33 cm (width)
1. 7x - 28 = 84
2. 7x = 112
3. x = 16
