For this case we have the following expression:
 (ab) ^ - 2
 Rewriting the expression we have:
 (ab) ^ - 2 = 1 / (ab) ^ 2
 Then, for power properties we have:
 1 / (ab) ^ 2 = 1 / (a ^ 2b ^ 2)

 Answer:
 The simplified expression is:

Is 4/5 greater or less than 45/100 how do you know
rusak2 [61]

Answer:

4/5 is grater than 45/100

Step-by-step explanation:

Why?

because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%

now to make 4/5 a percentage what times 5 = 100?

20 does

so you times the top and bottom by 20

4*20= 80

now your fraction is 80/100  (top # tells you the %)

it's 80%

80% is grater than 45%

Please help, thank you!
Nadya [2.5K]

Answer:

37 and 26

Step-by-step explanation:

Let the bigger number be x and the smaller number be y.

Then the two numbers total 63 will give us:

y+x=63------>eqn1

The two numbers have a difference of 11.

y-x=11------->eqn2

We add equations 1 and 2 to obtain:

2y=74

Divide both sides to get:

y=37

Put y=37 into eqn2 to get:

37-x=11

x=37-11

x=26

This larger number is 37 and the smaller number is 26
