This game isn't too bad.
We have a proportion which represents another number.
Basically the problem states that the ratio:
22/40 is applicable to the ratio of:
# Wins / # Games
I'll represent the # Wins with the letter W.
and I'll represent the # of Games with the letter G.
So we simply set them equal to each other.
22/44 = W / G
They gave us G = 162 games
22 / 44 = W / 162
Cross multiply. So, the denominator on the left side of the equation will multiply with the numerator on the right. While the denominator on the right multiplies with the numerator on the left.
44*W = 22*162
You'll probably need a calculator for 22*162, but you can use long multiplication if it isn't allowed.
44W = 3564
Divide 44 on both sides.
W = 3564 / 44
W = 81
C. 81 is our answer!
Write the division as a fraction
2/3x - 8 = 9
Multiply both sides of the equation by 3
2x-24=27
Move the constant to the right and change the sign
2x=27+24
Add the numbers
2x=51
Divide both sides by 2
2x/2=51/2
X= 25.5
Answer:
last year = 530570
this year = 424456
decreased plants = 530570-424456 = 106114
decreased percent = 106114÷530570×100%
= 20%
therefore 20% is the decrease precent in the number of potted plants ordered anually
Remember PEMDAS (Parenthesis, Exponents, Multiplication, Divison, Addition and Subtraction)
Also note that Multiplication and Division needs to be done left to right and the same goes for Addition and Subtraction.
So in your problem, the first operation we need to do is division.
68 - (18/3) x 6
68 - 6 x 6
Now we do multiplication
68 - 6 x 6
68 - 36
Finally we do subtraction because that's the only operation we have left to do
68 - 36 = 32
So your answer should be 32.
