Answer:

Step-by-step explanation:

We need to simplify this equation:

6.9 - 5 + 4.1

The reason why there is a negative sign in between 6.9 and 5 is that + and - become negative.

There is a chart that can help you with this:

+ + = +

+ - = -

- + = -

- - = +

This will help you with BIDMAS/BEDMAS

Answer: 1/4 full.

Step-by-step explanation:

The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.

There is currently 3/4 of the tank remaining.

To find 2/3 of 3/4, you can multiply the fractions together.

Do this by multiplying both numerators and both denominators:

$\frac{2}{3} *\frac{3}{4} = \frac{2*3}{3*4} = \frac{6}{12}$

Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).

3/4 - 2/4 = 1/4

There will be 1/4 of the tank left.
