<u>Convert a Repeating Decimal to a Fraction
</u>
We need to convert the following decimal to a fraction:

Let's call x to the given number:

The number has two repeating (periodic) decimals, thus we multiply by 100:

Note the decimals continue to repeat exactly like the original number.
Subtracting both expressións, the repeating decimals are simplified:

Operating:
99x=-37
Dividing by 99:

The fraction cannot be simplified, thus:

hope u can do..
The probability that the first horse wins is 2/7. The probability that the second horse wins is 3/10. Since the events that the first horse wins and the second horse wins are shared exclusive, the probability that either the first horse or the second horse will win is :
2/7 + 3/10= 41/70
Hope this is correct.
Answer:
(x-4)(x+5)
Step-by-step explanation:
Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)
