What is 89/100 as a percent?
masya89 [10]
89/100 as a precent is is 89% because if you change 89/100 to a decimal you get .89 and then you multiply that by 100 (or just move the decimal over 2 places to the right) and you will get 89% make since? and its the same way if your going from % to decimal except you divide by 100( or move the decimal over 2 places to the left) so to a percent is right and to a decimal is left. easy right?

Bhavik bought 333 liters of milk and 555 loaves of bread for a total of \$11$11dollar sign, 11. A month later, he bought 444 lit
AnnZ [28]

Let the price of 1 litre of milk be  x$

Let the price of 1 loaf of bread be y$

According to the problem

333x + 555y =11

444x+444y=10

On subtracting the two,

We get

(333x+555y=11) * 444

(444x+444y= 10) * 333

(-)     (-)         (-)

147852x + 246420y =4884

147852x + 147852y = 3330

(-)            (-)                  (-)

------------------------------                   

 98568y = 1554     

           y = 1554/98568     

              = 0.0157$          

                 =0.02$    

Price of 1 loaf of bread= 2 cents    

On putting the value of y 

333x + 555*0.0157 = 11333x  + 8.7135 = 11333x = 2.2865x = 2.2865/333x = 0.00068$   = 0.01$

Price of 1 litre of milk = 1 cent
