How do I know my multiples

One way to make it easier to multiply, pick a number from a multiplication problem. Then, add the amount of times of the other number.

Example:

6 x 8 = ?

8 = Chosen Number

So, add 8, 6 times.

8 + 8 + 8 + 8 + 8 + 8 = ?

? = 48

Which, 6 x 8 does equal 48.

answer: add the !

step-by-step explanation: then we will answer

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
