Question

Simplify 2x2/10x3-2x2.

Answer 1

Answer:

$- \frac{14}{5} = - 2 \frac{4}{5} = - 2.8$ where necessary

Step-by-step explanation:

So, we are to simplify: $2 \times \frac{2}{10} \times 3 - 2 \times 2$

First of all, divide the fraction.

$2 \times \frac{1}{5} \times 3 - 2 \times 2$

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

$\frac{6}{5} - 4$

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

$\frac{6}{5} - \frac{4}{1} = \frac{6 - 20}{5}$

→$- \frac{14}{5} = - 2 \frac{4}{5} = 2.8$

I hope this helps
