Answer:
- 32
- 2
Explanation:
To answer these question we have to substitute the values we are given into the question!
1)

We are told that x is 4 and y is 2.4, this makes our question

Now we can solve it!
- 4 + 2.4 = 6.4
- 12 x 6.4 = 76.8
- 76.8 ÷ 2.4 = 32
The answer is 32!
2)

We are told that a is 6 and b is 3, this make our question

Now can solve it!
- 6 - 4 = 2
- 3 x 2 = 6
- 6 ÷ 3 = 2
Hope this helps, have a lovely day! :)
