Okay this should be simple. So take 10 times 3. Because those are diagnal to eachother. 10*3 = 30. Now take 30 divided by 7. 30/7 = 4.28 and rounded would be just 4.2. That's your answer! Hope i helped! 

Describe and correct the error in finding the product
2/5×3/10=6/50=3/25

Answers

Answer: There is not error in finding the product. The result is: =(3)/(25)


Step-by-step explanation:

1. You have the following multiplication shown in the problem above:

(2)/(5)*(3)/(10)

2. To solve it you must multiply the numerators and multiply the denominators, as you can see below:

(2*3)/(5*10)=(6)/(50)

3. When you simplify the product, you obtain the following result:

=(3)/(25)
