What is 2.5 x 7/10 =? and how did you get the answers?
Ivan

Answer:

1.75 or  \frac{35}{2}

Step-by-step explanation:

2.5 * 7/10 is just like 2.5 * 0.7

so 2.5 * 0.7 = 1.75

You could also convert 2.5 to fraction which is 25/10

so you would have \frac{25}{10} * \frac{7}{10} = \frac{175}{100} reduced would  equal \frac{35}{2}

How this helps you! :)

Could you please mark this answer as brainiest?

It would help me!

Thank you!
