Answers

(4)/(5) × (5)/(8)

First, apply this rule: (a)/(b) × (c)/(d) = (ac)/(bd) / Your problem should look like: (4x5)/(5x8)
Second, simplify 4 × 5 to 20. / Your problem should look like: (20)/(5x8)
Third, simplify 5 × 8 to 40. / Your problem should look like: (20)/(40)
Fourth, simplify. / Your problem should look like: (1)/(2)

Answer as fraction: (1)/(2)
Answer as decimal: 0.5
(4)/(5) * (5)/(8) = (4:2)/(5:5)* (5:5)/(8:2) \n\n~~~~~~~=2* (1)/(4) \n\n~~~~~~~= (2)/(4)

You have 5 pounds and 10 ounces of laundry. Your washer has a capacity of 7 pounds. How many more ounces of laundry would you need to make a full load?

Answers

7 pounds = 16 pounds and 1 pound = 6 pounds and 16 ounces.

(6 pounds + 16 ounces) minus (5 pounds + 10 ounces) = 1 pound + 6 ounces 
(6pounds+16ounces)-(5pounds+10ounces)=1pounds +6ounces

Explain the different ways it is possible to add two rational numbers and get a negative number

Answers

Answer:
both numbers are negative
negative number is greater than the positive number

Explanation:
In order to add two rational numbers and get a negative value, one of two scenarios should occur:
1- both numbers are negative.
In this case, the answer would definitely be negative as the two numbers are originally negative
Examples:
-9 + -2 = -9 - 2 = -11
(-1)/(2) + (-3)/(2) = (-4)/(2) = -2

2- negative number is greater than the positive number
In this case, the negative sign would dominate and the result would be negative
Examples:
-9 + 3 = -6
(-5)/(6) + (2)/(6) = (-3)/(6)

Hope this helps :)

-- If both of them are negative,

or

-- If their signs are different and the negative number has
a bigger absolute value than the positive one,

then

-- Their sum is negative.

Actually, I don't think it matters whether they're rational or not.
