So percent means parts out of 100 so
1%=1/100
so 9/20=x/100
a hack withought using legit math is
20 times 5=100 so
9/20 times 5/5=x/100
9 times 5=45
20 times 5=100
45/100
45% is the answer

Answer:
See below.
Step-by-step explanation:
-7(6) = -42
-1(-10) = 10
2(-5) = -10
-3(-14) = 42
-32/-4 = 8
-2(-2)(-2) = -8
Answer:
4,5,6 are the three consecutive numbers. 16, 25 and 36 are their squares.
Step-by-step explanation:
Let the three consecutive numbers be x, (x+1), (x+2)
Now, the squares of these three numbers are 
Sum = 77
∴by the problem ,

{Taking 3 common }

{By factorization}

Therfore,

<em>X can't be negetive </em>
∴ 
The squares of the three consecutive numbers are 16, 25, 36
The three consecutive numbers whose sum is 77 are 4, 5, 6
