Answer 1

Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.

So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.

You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.

You get 3/1 × 1/1 = 3

It equals to 3

Then, 4(2.6) = 4 × 2.6 = 10.4

2(-3) = +2 × (-3) = -6

When you multiply a positive number for a negative one, you'll always get a negative number.

Sum all the results.

3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4

Final answer: -13,4

Answer 2

9* 1/3 = 3

4*2.6 = 10.4

2*-3 = -6

3-10.4 +-6 =

3-10.4 = -7.4 +-6 = -13.4
