Example Question #3 : How To Find A Solution To A Compound Fraction
Convert to an improper fraction.
To convert into an improper fraction, take the whole number and multiply that with the denominator .
Then, we add that to the numerator which is .
Then we take that sum and put it over th denominator which gives us an answer of:
.
Example Question #4 : How To Find A Solution To A Compound Fraction
Simplify.
Lets focus on the left fraction. Lets try to have three fractions multipled altogether. To acheive this, we can multiply the numerator of the left fraction with the reciprocal of the denominator.
Thus, mutliple the numerator and denominator by .
Now we have . We can simplify this by crossing out the to a and the to a .
Then, cross out the into a and the into a . It should look like this:
.
Multiply it out and you will get the answer.
Example Question #5 : How To Find A Solution To A Compound Fraction
Solve and simplify.
Convert both numerator and denominators into fractions. Convert the integers first to fractions.
Now that our numerator and denominator have a common denominator between their fractions we can subtract them.
Then multiply top and bottom by as that is the reciprocal of the denominator and when dividing fractions, it is the same as multiplying the numerator by the reciprocal of the denominator.
Then reduce by crossing out the into a and the into a .
Then multiply to get the answer.
Example Question #1 : Compound Fractions
Solve and simplify.
Remember PEMDAS, the order of operations for dealing with expressions which is the acronym that stands for (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
Multiplication has priority over addition. Looking at the fractions that are multiplied together we can see the is reduced to and the into a .
The new fraction becomes:
Then find least common denominator. In our case it will be 70.
.
Then add it all up to get the final answer.
Example Question #3 : Compound Fractions
Simplify.
Remember PEMDAS. Take care of the parentheses first and find least common denominator of the fractions. Next distribute, then add and finally, subtract.
Working with the parentheses we get:
Reduce the to and the to . Then reduce to and to .
Multiply first then subtract.
If I divide the left fraction by , I should be able to match the denominator of the right fraction and also I can subtract easily.
Example Question #3 : Decimals
Express as a decimal.
Divide 8 by 15:
The 3 repeats, so the correct choice is .
Example Question #4 : Decimals
Give the decimal equivalent of .
Divide 11 by 18:
The 1 repeats infinitely, so this can be rewritten as .
Example Question #5 : Decimals
Give the decimal equivalent of .
Divide 5 by 27:
The group "185" repeats infinitely, so this can be written as .
Example Question #6 : Decimals
Give the decimal equivalent of .
Divide 7 by 36:
The 4 repeats infinitely, so this can be rewritten as .
Example Question #1 : Decimals With Fractions
Write the value of this expression as a decimal:
Simplify the sum by taking the least common denominator, which is 12:
Divide 13 by 12:
