Question

3•X=2,7 HELP HELP HELP HELP

Answer 1

We want to solve for x the following equation

$3x=2.7$

To solve this, we can divide both sides by 3. To divide 2.7 by 3, first, let's multiply both numbers by 10.

$\frac{2.7}{3}=\frac{27}{30}$

Now, we can divide both numerator and denominator by 3

$\frac{27}{30}=\frac{27/3}{30/3}=\frac{9}{10}$

Now it is easy. To divide by 10 is the same as "moving" the dot to the left.

$\frac{9}{10}=0.9$

Then

$x=0.9$
