how do I add odd number fractions for example 5/9 and 3/5?
Answer:
if the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To do this, you need to find at least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with common denominator. Then add and simplify
Answer:
[tex]\frac{52}{45}[/tex] or [tex]1\frac{7}{45}[/tex]
Step-by-step explanation:
In order to add two fractions with different denominators, you will have to find its least common denominator (LCD):
The LCD of 9 and 5 is 45.
Next, we'll start with 5/9:
Divide 45 by 9, which results in 5. Then, multiply the numerator by 5:[tex]\frac{5}{9} = \frac{5*5}{45} = \frac{25}{45}[/tex]
The same goes with 3/5:
Divide 45 by the denominator, 5, then multiply 5 by the numerator 3:
[tex]\frac{3}{5} = \frac{9*3}{45} = \frac{27}{45}[/tex]
Now, we can finally add 25/45 and 27/45 since they have the same denominator. Doing so results in a sum of 52/45:
[tex]\frac{25}{45} + \frac{27}{45} = \frac{52}{45}[/tex]
If you have to transform 52/45 into a proper fraction (which will result in a mixed fraction), then it will be [tex]1\frac{7}{45}[/tex].

Step-by-step explanation:
Does -a ? = (-a)?? Explain why or why not.
Explanation:
Always remember that variables have coefficients (x is the same as 1·x or 1x).
Raising a base to either an odd or even exponent has particular rules when it comes to signs:
If you raise -a² = -a² because a has a coefficient of - 1. This implies that -a² = -1a². Now, raising -a³ (odd exponent) still results in -a³ because you're only raising the base, a, to its exponent, and it doesn't include its coefficient of -1. Hence, -a³ = -1a³ = -a³.Also, (-a²) = -a² because once again, you're only raising the base, a, and not its coefficient (even if both are inside the parenthesis).It will be different if the base is raised as follows:
(-a)² = a² because the coefficient, -1, is included within the parenthesis. It is the same as (-1a)² = 1a² or a².(-a)³ = -a³ or -1a³ because it is an odd exponent, and if you raise a negative base to an odd exponent results in a negative value of the base.The key is that the exponent outside the parenthesis will affect both the coefficient and its base, such as (-a)².

Calculate the % loss
Cost price of an article =$28
Selling price of the article=$21
The loss in percentage is 25%.
Given that,
Cost price of an article = $28
Selling price of the article = $21
We know that,
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Now loss can be calculated by subtracting selling price from cost price,
Therefore,
28 - 21 = 7
Hence there are loss of $7 in business,
Now to calculate percentage loss,
Divide loss by cost price then multiply with 100,
Then,
⇒ (7/28)x100
⇒ 25%

many weeks will it take her to save enough to buy it?
a. Define the variable and represent the situation with
an equation.
x = number of weeks which is some positive whole number
50x = amount saved after x weeks, when saving $50 per week
50x+800 = add on the 800 she already has
The expression 50x+800 is the total money saved. We set this equal to the 1150 to set up the equation we're after
