Answer:
the first expression
Step-by-step explanation:
Answer:
3.5 tons
Step-by-step explanation:
Divide the pounds for the male by the amount of tons it is.
8000/4 = 2000
This is how many pounds are in one ton. Divide the weight of the female by this.
7000/2000 = 3.5
The female weighs 3.5 tons.

To multiply these numbers, the first step is to writhe "-8" as an improper fraction, to do so, divide it by 1

Next is to solve the multiplication, to do so, first multiply the first two terms of the multiplication:

The multiplication is between two negative numbers, when you multiply two negative numbers, the minus signs cancel each other and turn into a positive value, this is called "double-negative"

Next multiply the result by the third fraction -2/5
This time you are multiplying a positive and a negative number, so the result of the calculation will be negative

Final step is to simplify the result, both 144 and 15 are divisible by 3, so divide the numerator and denominator by 3 to simplify the result to the simplest form:
Answer: 270
Step-by-step explanation:
Length x width= area
15x 18= area
15 x 18= 279
