Without using a calculator convert the decimal into a fraction<br> 0. 75
mojhsa [17]

Step-by-step explanation:

Decimals can always be put over 1, as they're part of a whole number.

\frac{0.75}{1}

<u>Multiply both numerator and denominator by 100:</u>

<u />\frac{0.75 \times 100}{1\times 100} =\frac{75}{100}

\frac{0.75}{1} \: and \: \frac{75}{100} \: are \: fractions \: of \: 0.75

What is the greatest fraction you can make using the digits 4, 7, and 9?
wel

Answer:

  (7^9)/4 = 40,353,607/4

Step-by-step explanation:

Assuming each digit is used once and exponentiation is allowed, the largest numerator and smallest denominator will result in the largest fraction.

__

If other functions, such as factorial are allowed, then there might need to be a limit on the number of times they are applied. For example,

  (7!)^(9!)/4 has about 1 million digits

something like ...

  ((7!)^(9!))!/4 has many more digits than that

and you can keep piling on the factorial symbols to any desired depth.
