The improperfraction of 1(1/3) is 4/3.
A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
1 and 1/3
An improperfraction means the numerator is greater than the denominator.
So,
1 and 1/3
= 1(1/3)
= (3 x 1 + 1) / 3
= 4/3
4 > 3 so it is an improperfraction.
Thus,
The improperfraction of 1(1/3) is 4/3.

Answer:
4/3
Step-by-step explanation:
to change a mixed number to an improper fraction, you have to multiply the denominator by the whole number and add the numerator to the product. This is your numerator. The denominator stays the same.
Thus,
Numerator = 3 x 1 +1 = 4
Denominator = 3
Fraction = 4/3

54 miles/hour
If he made two stops of 10 minutes each and maintains the same speed, it would take him more than 4 hours to reach the town as the time speed would have been extended by 20 minutes.
Step-by-step explanation:
The rate of change of distance with time is called speed and it is measured in miles per hour. Mathematically,
Speed = Distance/time
His rate in miles per hour is his speed
= 216/4
= 54 miles per hour
Answer:
Rate in miles per hour: 54 miles per hour
Step-by-step explanation:
rectangular pyramid
cylinder
triangular prism
Answer:
Rectangular pyramid
Step-by-step explanation:
The three dimensional shapes can be cut through planes perpendicular or parallel to the base.
Here, the shapes are being cut parallel to the base.
Since, cone cylinder and triangular prism are identical when cut by planes that are parallel to the base.
Rectangular pyramid do not have identical cross sections.
Option (b) is correct.
b. 70 <= 82 + 88 + n / 3 <= 85; 80 <= n <= 85
c. 80 <= 82 + 88 + n / 3 < 85; 70 < n < 85
d. 82 <= 80 + 85 + n / 3 <= 88; 70 <= n <= 85
Answer : option A
Jackie scored 82 and 88 on her first two quizzes
Let n be the score of third quiz
Average of 3 quiz =
average between 80 and 85, inclusive.
so average lies between 80 and 85
Question says 80 and 85 inclusive. so we use <= or >= symbol
So inequality becomes
( multiply all sides by 3)
(subtract all sides by 170)
so option A is correct
