Answer:
The 40% marked up price of refrigerator is $1260.
Step-by-step explanation:
The cost price of the refrigerator = $900
Now, the mark up should be 40%
Calculating the markup on the cost price , we get
40 % of $900 = 
or, 40 % mark up = $360
Now, the Marked up cost = Cost Price + Marked up Price
= $900 + $360 = $1260
Hence, the 40% marked up price of refrigerator is $1260.
23/27 because 46/54 diveded by 2 equals 23/27 which can not be simplified any further
Find the number in the tenth place 0 and look one place to the right for the rounding digit 9. Round up if this number is greater than or equal to 5 and round down if it is less than 5.
Answer: 0.1
False ......................................
They are not in proportion, since its 6:9 round it down (2:3) so pretend the 6 are apples and the 9 are oranges
Every 2 apples there are 3 oranges
So having 9 apples what is that?
2 x ? = 9
2 x 4.5 = 9
So if you want to keep 2:3 you have you times the oranges by 4.5 aswell!
3 x 4.5 = 13.5
So since it is 9:12 not 9:13.5 they are not in proportion
