What is 140% of 310? Round to the nearest hundredth (if necessary)

434

Step-by-step explanation:

we want 140% of 310. This means that the 100% is 310.

We can represent this as a table:

 Quantity        Percentage

      310      ⇔      100%

I will call "x" the unknown quantity of the 140%:

 Quantity        Percentage

      310      ⇔      100%

       x        ⇔      140%

And we can solve this problen using the rule of three which is to multiply the cross quantities in the table (310 and 140) and divide the result by the remaining amount (100):

x = 310*140/100

x = 43,400/100

x = 434

another way to get the result is to multiply 310 by 1.4 which is the equivalent of 140%:

x = 1.4*310

x = 434

one that is bigger than 3 1/2

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
