how do you solve 15 divided by 2/9

Answers

Answer:

67.5 or 67 1/2

Step-by-step explanation:

15   ÷              2

         ___________            

                   9

The numbers in 15 divided by 2/9 are labeled below:

15 = whole number

2 = numerator

9 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

15 x 9 2  =     135

                       ____

                          2

Thus, the answer to 15 divided by 2/9 in fraction form is:

 135

_____

   2

To make the answer to 15 divided by 2/9 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

135 / 2 = 67.5

The answer is rounded to the nearest two decimal points if necessary.

135/2 is an improper fraction and should be written as 67.5 or 67 1/2.

Hope this helps, have a nice day/night! :D

Answer:

67.5

Step-by-step explanation:

15 = 135/9

135/9 x 9/2 = 15 x 4.5 = 67.5

            9/2 = 4.5

The equation of the line is y = 7x + 2.

What is the equation of a line?

The equation of a line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

m = 7 and c = 2

The equation of a line is,

y = mx + c

y = 7x + 2

Therefore, the equation of the line is y = 7x + 2.

Answers

Divide 296 by 16 you get 18.5 then add the 5.75 to get 24.25
So the answer is 24.25

The regular price of a ticket to the game will be $24.25  based on the given data.

What is a number system?

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given,

Total paid = $296

Number of tickets = 16

Cost per tickets = 296/16 = $18.5

This cost excludes the $5.75 saved due to the group.

Original price = $18.5 + $5.75 = $24.25

Hence "The regular price of a ticket to the game will be $24.25  based on the given data".

What is the weight of a dry substance in 150 g of a 3% substance solution?

Answers

4.5 g 56.25 g Since the only type of measurement mentioned in this question is weight or mass, I'll assume that the percentage concentration is % m/m (mass/mass). For that type of concentration measurement, simply multiple the percentage by the total mass to get the mass of the desired substance. So 150 g * 3% = 150 g * 0.03 = 4.5g For the amount of 8% solution with the same amount of dry substance, there's 2 ways of calculating the mass of solution. First, use the ratio of percentages, multiplied by the mass of the original solution to get the desired amount of new solution: 3/8 * 150 g = 56.35 g Or calculate it from scratch, like 4.5/X = 8/100 450/X = 8 450 = 8X 56.25 = X In both cases, the result is that you desire 56.25 grams of 8% solution.
