You can make a common denominator, then multiple the top by said denominator, then cross it out - because they are the same
Answer:
Step-by-step explanation:
Given:
The ratio of the amount of money Kate has to that of Nora is 3 : 5.
After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.
To find:
The sum of money Kate had initially.
Solution:
Let the initial amount of money Kate and Nora have are 3x and 5x respectively.
After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.
The amount of Kate = 3x+150
The amount of Nora = 5x-150
Now,
Divide both sides by 8.
Putting x=300 in 3x, to get the amount of money Kate has initially.
Therefore, the Kate initially had $900.
The rectangle is 36 x 24 cm.
36+36+24+24=120
Not gonna lie I guess and checked on this but I hope this helped! :D
