Make it the same denominator so you can add them (18.)
Multiply 5/9 by 2 and multiply 4/6 by 3.
10/18 + 12/18 = 22/18.
Since there is not 22/18 listed, you can use this fraction as a proportion. The only proportion that can be evident is answer A, as when you multiply 22/18 by 3, you get 66/54.
Hope this helps! ;)

A drawing has a scale of 1:40 on the drawing a bedroom is a rectangle measuring 10 cm x 18 cm a kitchen has an actual area of 300,000 cm² which has the bigger actual area of the kitchen or the bedroom
Answer:
The kitchen has a bigger actual area than the bedroom
Step-by-step explanation:
Here, we want to know the compartment with the bigger area
Since the bedroom has a drawing measure of 1 to 40; compared to the actual measurement;
The real dimensions will be;
10 * 40 and 18 * 40
= 400 by 720
So, its area which is length * width will be;
400 cm * 720 cm = 288,000 cm^2
we can see that the kitchen with an area of 300,000 cm^2 is bigger than this area of the bedroom

PLEASE HELP MEEE!!!!
Answer:
The correct option is;
B, C, and D
Step-by-step explanation:
The labelled letters on the number line are;
A = 2 units to the left of the point 0 = - 2 units
B = 1 units to the left of the point 0 = - 1 unit
C = Located at the point 0
D = 1 units to the right of the point 0 = +1 unit
Therefore, the letters that have their opposites labelled are;
Given that we have;
The opposite of B = -1 is +1 = D
The opposite of D = +1 is -1 = B
The opposite of C = 0 is 0 = C
The letters which have their opposites labelled are B, C and D

The Jackson's dinner cost $125. They left $21.25 as a tip. What was the percentage of the tip? Please explain and help me! THANK YOU!!!
Answer:
17%
Step-by-step explanation:
to find the percentage of something, you have to fill out the following formula:
x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:
125x = 2125
then you have to divide, to single out x:
the answer is 17
so it is 17%
