let , $a\ge b$
$\therefore a=G\cdot m$ and $b=G\cdot n$
$a-b=Gm-Gn=G(m-n)$
Now, $\gcd(a-b,b)$ clearly is, $G$
Answer:
25%
Step-by-step explanation:
divide 3000 by 750 And you get 4. in percentages that would be 1/4 or 25%
In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.
The number in the 4 sections are 100, 80, 70, and 56.
A 2 x 2 array that shows the problem 18 x 17.
2 x 2 array has four blockers or magic quadrants, the matrix diagram is a simple square divided into four equal quadrants.
18 = 10 +8
17 = 10 +7
18 x 17 = 306
In the 2 x 2 array : 100+80+70+56 = 18 x 17 = 306
Therefore, In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.
Boys : Girls = 3 : 5
3 + 5 = 8 parts
<u>Find 1 part:</u>
8 parts = 40 students
1 part = 40 ÷ 8 = 5 students
<u>Find number of boys and girls:</u>
3 parts = 3 x 5 = 15 girls
5 parts = 5 x 5 = 25 boys
Original Number of students = 15 : 25
<u>Find new ratio:</u>
New Ratio = 15 + 3 : 25 - 1 = 18 : 24 = 3 : 4
Answer: 3 : 4
If the number after 3 is 1 then the answer is 48j-132
