What is 6 3/4 divided by 2 5/8?

Answers

Conversion a mixed number 6 3/4 to a improper fraction: 6 3/4 = 6 3/4 = 6 · 4 + 3/4 = 24 + 3/4 = 27/4.

To find new numerator:

Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4 = 24/4

Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

Write a previous answer (new numerator 27) over the denominator 4.

Six and three quarters is twenty-seven quarters

Conversion a mixed number 2 5/8

to a improper fraction: 2 5/8 = 2 5/8 = 2 · 8 + 5/8 = 16 + 5/8 = 21/8

To find new numerator:

Multiply the whole number 2 by the denominator 8. Whole number 2 equally 2 * 8/8 = 16/8

Add the answer from previous step 16 to the numerator 5. New numerator is 16 + 5 = 21.

Write a previous answer (new numerator 21) over the denominator 8.

Two and five eighths is twenty-one eighths

Divide: 27/4 : 21/8 = 27/4 · 8/21 = 27 · 8/4 · 21 = 216/84 = 12 · 18 /12 · 7 = 18/7

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/

8 is 8/21) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 12 gives 18/7.

In words - twenty-seven quarters divided by twenty-one eighths = eighteen sevenths.

The solution of the expression [tex]6 \dfrac{3}{4}[/tex] divided by [tex]2 \dfrac{5}{8}[/tex] , which are in mixed fraction is [tex]\dfrac{18}{7}[/tex]

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

The combination of a whole number and a proper fraction is called as mixed fraction.

The following expression can be simplified as:

Here, both the fraction are converted into improper fraction as[tex]\dfrac{27}{4}[/tex] and, [tex]\dfrac{21}{8}[/tex]

Now, the following expression is simplified as:

[tex]\dfrac{\dfrac{27}{4}}{\dfrac{21}{8}}[/tex],

Reciprocal the expression, so that the division sign changes to multiplication.

[tex]\dfrac{27}{4} \times \dfrac{8}{21}[/tex]

Thus, the solution will be [tex]\dfrac{18}{7}[/tex].

This diagram shows three small squares and two rectangles composed of 10 small squares, Jade says this diagram can represent 230. What does a small square represent for Jada? Name a number greater than 230 that can also represent.
Lin says this diagram can represent 2.3, what does a small square represent for Lin. Name a number of less than 2.3 that this diagram can also represent.

Answers

Answer:

Step-by-step explanation:

From the figure

A small square represents 10 for Jade's diagramA small square represents 1 for Lin's diagram

From the figure, we have:

Rectangles = 2 (20 squares)

Square = 3

Represent 1 square with x.

So, the number is represented as:

[tex]Number = 20x + 3x[/tex]

[tex]Number = 23x[/tex]

Jade says the number represents 230.

So, we have:

[tex]23x = 230[/tex]

Divide through by 23

[tex]x = 10[/tex]

This means that:

A small square represents 10 for Jade's diagram

Lin says the number represents 23.

So, we have:

[tex]23x = 23[/tex]

Divide through by 23

[tex]x = 1[/tex]

This means that:

A small square represents 1 for Lin's diagram

Answer:

Use estimation

Step-by-step explanation:

A) 99 + 54

estimate that 99 is 100

estimate that 54 is 55

Add 100 and 55 together

100 + 55 = 155

Remember that you added 1 to 99 and 1 to 55

So you must subtract 2 from 155

155 - 2 = 153

Your answer is 153.

B) 244 - 99

estimate that 244 is 245

estimate that 99 is 100

Add 245 and 100 together

245 + 100 = 345

Remember that you added 1 to 245 and 1 to 99

So you must subtract 2 from 345

345 - 2 = 343

Your answer is 343.

Remember that you are doing all of this in your head!
