Evaluate:
To divide any number by a fraction, we can multiply that number by the reciprocal of the fraction. That means:
So we have:
Example Question #912 : Hspt Mathematics
Simplify:
Multiply each term by 6:
Example Question #913 : Hspt Mathematics
Evaluate:
A mixed number represents the sum of an integer and a fraction. In order to evaluate this problem first we need to change the mixed number ( ) to an improper fraction. Improper fractions are fractions whose numerator is greater than the denominator. So we can write:
Now we should evaluate and we have:
Example Question #914 : Hspt Mathematics
Simplify:
We can first find a common denominator for the expression in the numerator, which is . This gives us:
Example Question #915 : Hspt Mathematics
Which of the following is the reciprocal of ?
First, rewrite this as an improper fraction:
The reciprocal of an improper fraction can be found by switching its numerator and denominator, retaining the negative sign, so the reciprocal is .
Example Question #916 : Hspt Mathematics
Which of the following is the reciprocal of 2.8?
First, rewrite this as an improper fraction:
The reciprocal of an improper fraction can be found by switching its numerator and denominator, so the reciprocal is .
