Answer:
She did not consider the multiplicative inverse property of a real number
Step-by-step explanation:
Jacinta in her conclusion did not consider the Multiplicative Inverse property of real numbers.
Let x be an irrational number.
So, 
If x is an irrational number, then its reverse is also an irrational number. So by the Multiplicative Inverse property their product is 1 and 1 is a rational number. Thus, Jacinta was incorrect.
Answer:
Decrease
Step-by-step explanation:
So, I encourage you to grab a calculator and see for yourself
Put in the function: 4/5 into a standard calculator. You will see that it will come out to .8
Put in the function: 3/5 into a standard calculator. You will see that it will come out to .6
.6 is less than .8, just as 3/5 is less than 4/5.
Another analogy that can be used is seeing the fraction as a real-life object.
Let's say that you make two pies. You cut the pie evenly into five slices. You set them on the table and leave them for whoever wants to eat them. You see that Pie 1 has two slices missing (3/5) and that Pie 2 has one slice missing. (4/5)
3 out of 5 slices are left of Pie 1.
4 out of 5 slices are left of Pie 2.
Pie 1 has less than Pie 2 does.
Hope this has helped!

Answer:
Step-by-step explanation:
Price per ml of 80ml bottle= 0.68
price per ml of 50 ml bottle= 0.9
therefore two 50ml bottles is a better deal.
