The answer is C.

What fraction of 3 is 2 2/5
Yuki888 [10]

Answer: 2 2/5 is 4/5 of 3

Step-by-step explanation:

We can view that as what do we multiply 3 by to get 2 2/5 and call that value x

3x = 2 2/5

x = (2 2/5)/3

Let's turn 2 2/5 into an improper fraction... 2 2/5 = 12/5

So we have

x = (12/5)/3 = (12/5)(1/3) = 4/5

Thus 2 2/5 is 4/5 of 3

Verify:  3(4/5) = 12/5 = 2 2/5

How to multiply decimals when not using models​
sukhopar [10]

Answer:

You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.

Step-by-step explanation:

Say you were multiplying 14.63 and 7.74

                 

                   14.63

<u>                    x 7.74                 </u><em>Always starting from the right side of the equation</em>

                   .5852                <em>go to the left </em> <em>four digits and put a decimal then                   </em>

<em>                   ↑←←←←                just carry the decimal down and you'll  end up with  </em>

                 10.2410              <em>the final product</em>

<u>             + 102.4100                </u>

               113.2362
