Say you have 95 over 10. You put how many times 10 goes into 95, which is 9. Then you have 5 left over. You take 5 and put it over 10. You can simplify that to 1 over 2. Your mixed number would then be 9 and 1/2.
8 Broken toys : 42 total toys = 1 Broken toy : 6 total toys
20 Broken toys : 105 total toys = 4 Broken toy = 21 total toys.
Answer: No: They are not proportional.
5+a-4√(a+1)/(a-3) is the simplified form of the number. This can be obtained by multiplying numerator and denominator with conjugate of the denominator.
<h3>Simplify the number:</h3>
Given the number,
√a+1-2/√a+1+2
Denominator = √a+1+2
Conjugate of the denominator = √a+1 - 2
Now, (√a+1-2)(√a+1 - 2 )/√(a+1+2)(√a+1 - 2 )
=(√a+1 - 2 )²/(√a+1)² - 4
=(a+1 -4√a+1+5)/(a+1-4)
=5+a-4√(a+1)/(a-3)
Hence 5+a-4√(a+1)/(a-3) is the simplified form of the number.
