The question is equal to: 135 / 45
Divide:
135 / 45 = 3
3 = 300%
Answer = 300% (I think)

Answer:
5
Step-by-step explanation:
7/8=0.875
1/6=0.166
0.875 divided by 0.166 = 5.2
Answer:
5 inches wider
Step-by-step explanation:
The given area expression factors as ...
x² +2x -15 = (x -3)(x +5)
Apparently, we're to assume that these factors represent length times width, and the factor x-3 corresponds to a length that is 3 inches shorter than the old length (x). Then the width is (x+5), which is 5 inches wider than the old length.
Answer:
2
Step-by-step explanation:
Dividing by fractions is the same as multiplying by its reciprocal. So 8/6 divided by 4/6 is the same as 8/6 times 6/4
You can then solve this two ways.
1) Multiply like normal and simplify:
(8/6)(6/4) = 48/24 = 2.
2) Since there is a 6 in both the numerator and denominator, they cancel each other out. This leaves you with:
(8/1)(1/4). Multiply across like normal to get 8/4 = 2.
Answer:
a = -4
Step-by-step explanation:
Solve for a:
-7 (3 a - 1) = 91
Divide both sides of -7 (3 a - 1) = 91 by -7:
(-7 (3 a - 1))/(-7) = 91/(-7)
(-7)/(-7) = 1:
3 a - 1 = 91/(-7)
The gcd of 91 and -7 is 7, so 91/(-7) = (7×13)/(7 (-1)) = 7/7×13/(-1) = 13/(-1):
3 a - 1 = 13/(-1)
Multiply numerator and denominator of 13/(-1) by -1:
3 a - 1 = -13
Add 1 to both sides:
3 a + (1 - 1) = 1 - 13
1 - 1 = 0:
3 a = 1 - 13
1 - 13 = -12:
3 a = -12
Divide both sides of 3 a = -12 by 3:
(3 a)/3 = (-12)/3
3/3 = 1:
a = (-12)/3
The gcd of -12 and 3 is 3, so (-12)/3 = (3 (-4))/(3×1) = 3/3×-4 = -4:
Answer: a = -4
