<h3>What is a fraction?</h3>
A fraction is a part of a whole. It is also known as the number is expressed as a quotient, with the numerator is divided by the denominator.
Simple fractions are made up of both are integers.
Complex fractions has a fraction in the numerator or denominator
Proper fractions, have the numerator less than the denominator.
a. 31/ 2÷ 4
7/ 2 ÷ 4
Take inverse of the second number and multiply
7/ 2 × 1/ 4
Multiply through
7/ 8
b. 3 2/ 3 ÷ 1 4/7
11/ 3 ÷ 11/ 7
Take inverse of the second number and multiply
11/ 3 × 7/ 11
Multiply through
7/ 3
c. 1/ 2 + 3/ 4 + 5/ 6
Find the LCM
12 + 18 + 20/ 24
We the have;
50 / 24

Answer:
50 Degrees
Step-by-step explanation:
Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.

Answer:
The upper bound is 399.5
Step-by-step explanation:
Let's start by calculating the mean value of the distribution as the addition of all values given divided by 12:
Average = 289.75.
If the standard deviation is 56, then the upper bound in 95% the confidence interval for the mean price of the phones is going to be given by the mean value added to 56 times 1.96 (since 95% of the population is withing 1.96 times the standard deviation)
That is: 289.75 + 56 * 1.96 = 399.51
which rounded to one decimal place gives: 399.5
