Question

Simplify 2x2/10x3-2x2.

Answer 1

`- (14)/(5) = - 2 (4)/(5) = - 2.8` where necessary

Explanation:

So, we are to simplify:
`2 * (2)/(10) * 3 - 2 * 2`

First of all, divide the fraction.

`2 * (1)/(5) * 3 - 2 * 2`

Then, multiply the numerators on both sides of the minus sign.

`(6)/(5) - 4`

Now, it is clear you have to find the LCM of the denominators

`(6)/(5) - (4)/(1) = (6 - 20)/(5)`

→
`- (14)/(5) = - 2 (4)/(5) = 2.8`

I hope this helps
