Explanation:
- In the second step, I multiplied top and bottom by
- This is so we can apply the difference of squares rule in step 3. The difference of squares rule is (x-y)(x+y) = x^2-y^2.
- In step 4, the square roots cancel out with the squaring operation. The two operations are inverses of one another, which is why they cancel.
So in general, if the denominator is 
and you want to rationalize the denominator, then you should multiply top and bottom by 
. The same applies in reverse as well.
This leads to the denominator becoming 
Keep in mind that

Answer:
Chloe swam further. 16/40 to 25/40
Step-by-step explanation:
2/5 5/8
Find greatest common factor of 5 and 8 which is 40.
5x8=40 so multiply the same at the top.
2/5=16/40
5/8=25/40
16/40<25/40.

Kg to Pounds
8.3 kg in ponds is 18.26 lb
Kg to Ounces
8.3 kg in ounces is 292.16 oz
Step-by-step explanation:
We need to convert 8.3 kg to pounds and ounces
The conversion ratio is:
- 1 lb = 16 oz
- 1 kg = 2.2 lb
Converting kg to pounds(lb)
We know 1 kg = 2.2 lb
So, 8.3 kg = 8.3*2.2 lb
8.3 kg = 18.26 lb
So, 8.3 kg in ponds is 18.26 lb
Converting kg to ounces (oz)
We know that: 1 lb = 16 oz
We have converted 8.3 kg into 18.26 lb (pounds)
So, 1 lb = 16 oz
18.26 lb = 18.26*16 oz
18.26 lb =292.16 oz(ounces)
So, 8.3 kg in ounces is 292.16 oz
