The order for multiplication and division doesn't matter... @trentw882 could also first do the division then the multiplication

That's why it's P E M/D A/S Parenthesis, exponents, multiplication/division, then addition/subtraction

You should change this to be 26933.12 first then change to a fraction

trentw882:

ok

xxemilianaxx:

Do you know how to make it a fraction?

trentw882:

no

xxemilianaxx:

Well does it need to be an improper fraction or simplified?

trentw882:

it dose not matter

xxemilianaxx:

Mk well convert to a fraction by placing the decimal number over a power of 10, In easier word, Convert to a mixed number by placing the numbers to the right of the decimal over 100 Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator

trentw882:

ok

xxemilianaxx:

When you do it tell me what you get

trentw882:

idk

trentw882:

idk

xxemilianaxx:

Number: 26933.12 Whole . Decimal:26933.12 (Remember the 26933 for later) Just the decimal:.12 As a decimal fraction:\[\frac{ 12 }{ 100}\] The Greatest Common Factor of 12 and 100 is:4 Simplify the fraction:\[\frac{ 12/4 }{ 100/4 }\] Simplified:\[\frac{ 3 }{ 25}\] (Bring back the 26933) As a Mixed Fraction:\[26933\frac{ 3 }{ 25 }\] As an Improper Fraction:\[\frac{ 673328 }{ 25}\]
