Decrease £1280 by 60%
klemol [59]

Hi rainy here !!! so lets see lets set up your problem like this                              

X/1280 = 60%/100 so lets cross multiply

100 times X =100X

60 times 1280 = 76800

100X=76800 now lets divide each side by 100

100 divided by 100 = 0

76800 divided by 100 = 768

X=768 

So now we have to subtract to get the total amount so 1280 minus 768 = 512

512 is your answer :)

Hope I helped if u have any questions on how I did your problem feel free to message me or comment on my page bye !!!

Love ~Rainy~

9 and 1/4 are both rational numbers (which are numbers that can be represented in a fraction; 9 can be represented as 9/1)
And since it equals to 9/4 (or 2 1/4) the product is also a rational number.

Why can you multiply both quantities in a ratio by the same number to find an equivalent ratio? Please help I have this for home
weqwewe [10]

Answer:

  Multiplying by 1 does not change the ratio

Step-by-step explanation:

Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.
