What’s it like in fraction form though?
27
40
to a decimal using long division.
Answer: The number is 0,675
Step-by-step explanation:
Using long division you must divide the two numbers one by one.
Step 1: Because the numerator (27) is smaller than the denominator (40), you put the zero (0) first to add one zero to de right of the numerator.
270 / 40
Step 2: You will find the number that you can multiplicate 40 to get a number smaller than 270.
40 × 6 = 240
6 its the first number after the comma.
Then: 270 - 240 = 30 (the rest)
Step 3: Add another zero to 30 like you do in step 1 and do step 2 again
40 × 7 = 280
Then 300 - 280 = 20 (the rest)
Step 4: Now you have 20, add a zero and you have 200, that number its a multiple of 40, so your division finally is:
40 × 5 = 200
Now you have the three numbers after the comma of your result.
The value of the fraction number 27 / 40 using the long division method will be 0.625.
Division means the separation of something into different parts, sharing of something among different people, places, etc.
The expression is given as,
27 / 40
The value of the fraction number 27 / 40 using the long division method is calculated as,
40 ) 270 (0.675

We can write -
Cost of stool = $3
Cost of chair = $8
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have 6 stools and 4 chairs cost $58 but 5 stools and 2 chairs cost $35
Assume that the cost of a stool is $x and of a chair is $y. Then -
6x + 4y = 58 ..[1]
5x + 2y = 35 ..[2]
Eq[2] x 2, we get -
10x + 4y = 70 ..[3]
Eq[3] - Eq[1], we get -
10x - 6x = 70 - 58
4x = 12
x = 3
Cost of stool = $3
Cost of chair -
4y = 70 - 38
4y = 32
y = 8
Cost of stool = $3
Cost of chair = $8
Therefore, we can write -
Cost of stool = $3
Cost of chair = $8
