This calculator will first reduce the improper fraction to lowest terms by dividing numerator and denominator by the greatest common factor (GCF). The GCF of 45 and 10 is 5. The remainder is 1. With 1 as the numerator and 2 as the reduced denominator, the fraction part of the mixed number is 1/2.

Use this fraction calculator for adding, subtracting, multiplying and dividing fractions. Answers are fractions in lowest terms or mixed numbers in reduced form.

Input proper or improper fractions, select the math sign and click Calculate. This is a fraction calculator with steps shown in the solution.

If you have negative fractions insert a minus sign before the numerator. So if one of your fractions is -6/7, insert -6 in the numerator and 7 in the denominator.

Sometimes math problems include the word "of," as in What is 1/3 of 3/8? Of means you should multiply so you need to solve 1/3 × 3/8.

To do math with mixed numbers (whole numbers and fractions) use the Mixed Numbers Calculator.

Math on Fractions with Unlike Denominators

There are 2 cases where you need to know if your fractions have different denominators:

if you are adding fractions

if you are subtracting fractions

How to Add or Subtract Fractions

Find the least common denominator

You can use the LCD Calculator to find the least common denominator for a set of fractions

For your first fraction, find what number you need to multiply the denominator by to result in the least common denominator

Multiply the numerator and denominator of your first fraction by that number

Repeat Steps 3 and 4 for each fraction

For addition equations, add the fraction numerators

For subtraction equations, subtract the fraction numerators

Convert improper fractions to mixed numbers

Reduce the fraction to lowest terms

How to Multiply Fractions

Multiply all numerators together

Multiply all denominators together

Reduce the result to lowest terms

How to Divide Fractions

Rewrite the equation as in "Keep, Change, Flip"

Keep the first fraction

Change the division sign to multiplication

Flip the second fraction by switching the top and bottom numbers

Multiply all numerators together

Multiply all denominators together

Reduce the result to lowest terms

Fraction Formulas

There is a way to add or subtract fractions without finding the least common denominator (LCD). This method involves cross multiplication of the fractions. See the formulas below.Step-by-step explanation:

What is x equal to in this equation 5x-20<-5

kari74 [83]

The solution to given inequality is:

x<3

Step-by-step explanation:

We have to solve the given inequality to get the value of x

Given inequality is:

$5x-20$

Adding 20 on both sides

$5x-20+20$

Dividing both sides by 5

$\frac{5x}{5}$

The solution to given inequality is:

x<3

x will be equal to all values less than 3

help me plz you'll get brainliest if u show work and the only way for u to help me is if u show your work so plz do

Usimov [2.4K]

Answer:

Step-by-step explanation:

This will be D because the beaker already has 0.2 mL of water. If Jovita needs to add more water to the beaker, and then it is 0.8. In D, the diagram shows you 0.2 + x = 0.8, which makes it the right diagram.

Hope that helps!

Solve 2 1/2 divided by 5 1/3 = 8/x

ipn [44]

$2\frac { 1 }{ 2 } \quad divided\quad by\quad 5\frac { 1 }{ 3 } \\ \\ 2\frac { 1 }{ 2 } =2+\frac { 1 }{ 2 } =\frac { 5 }{ 2 } \\ \\ 5\frac { 1 }{ 3 } =5+\frac { 1 }{ 3 } =\frac { 15+1 }{ 3 } =\frac { 16 }{ 3 } \\ \\ \\ \frac { \frac { 5 }{ 2 } }{ \frac { 16 }{ 3 } }$

We're dividing fractions, so we will flip the one in the denominator upside down and we will multiply it with the numerator.

$\frac { \frac { 5 }{ 2 } }{ \frac { 16 }{ 3 } } \quad =\quad \frac { 5 }{ 2 } \cdot \frac { 3 }{ 16 } =\frac { 5\cdot 3 }{ 2\cdot 16 } =\frac { 15 }{ 32 }$

Let's equal this too 8/x

$\frac { 15 }{ 32 } =\frac { 8 }{ x }$

Cross multiply.

$8\cdot 32=15\cdot x\\ \\ 256=15x$

Divide both sides by 15.

$\frac { 256 }{ 15 } =\frac { 15x }{ 15 } \\ \\ \frac { 256 }{ 15 } =x$

(NOT A MULTIPLE CHOICE)

Vsevolod [243]

9514 1404 393

Answer:

a, b, c --- all not representative

Step-by-step explanation:

The question posed by the engineer is "are residents of the city in favor of ...".

The only representative sample is one from a pool that includes all residents of the city—not just those who (a) use the road, (b) live along the road, or (c) own homes.

Additional comment

The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.
