We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator. So we multiply 5 by 4, and get 20. Then we multiply 1 by 12, and get 12. Next we give both terms new denominators -- 12 × 4 = 48. So now our fractions look like this: Page 2
Spelled result in words is five thirds (or one and two thirds).
How do we solve fractions step by step?
Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts. Mixed numerals (mixed numbers or fractions) keep one space between the integer and fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2. Because slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3. Decimals (decimal numbers) enter with a decimal point . and they are automatically converted to fractions - i.e. 1.45.
5/12 - 1/4 as a fraction provides the detailed information about what is 5/12 minus 1/4 in fraction and decimal form, and the answer with steps to understand how it is being calculated by using different methods. 5/12-1/4 equals to 5/12 - 1/4 = [(5 x 4) - (1 x 12)]/(12 x 4) = (20 - 12)/48 = 8/48 = (8 x 1)/(8 x 6) = 1/65/12 - 1/4 = 1/65/12 minus 1/4 is equal to 1/6 where 5/12 is a fraction as a minuend, 1/4 is a fraction as a subtrahend, 1/6 is the difference between 5/12 and 1/4.5/12 minus 1/4 as a decimal 5/12 - 1/4 = 1/61/6 = 0.1667 5/12-1/4 as a decimal is 0.1667 where0.1667 is the difference between 5/12 and 1/4.
The below workout with step by step calculation shows how to find what is 5/12 minus 1/4 in simplest form by using the following methods: 1. LCM method, 2. Cross multiplication method. Problem and Workout - LCM Method: What is 5/12 minus 1/4 as a fraction? step 1 Observe the input parameters and what to be found: What to be found? 5/12-1/4 = ? Find what's the difference between 5/12 and 1/4. step 2 Compare the denominators of fractions 5/12 and 1/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/12 and 1/4 are not equal, it is said to be unlike fractions subtraction.
step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 5/12 and 1/4: step 4 Write the fractions 5/12 and 1/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions. step 5 Simplify the expression to have common denominator: step 6 Take the common values out and rewrite the above expression like the below: step 7Simplify the above expression further: 5/12 minus 1/4 equals to 1/6 in fraction. Problem and Workout - Cross Multiplication Method What to be found? 5/12-1/4 = ? Find what's the difference between 5/12 and 1/4. step 2 Find the product of numerator of Fraction A and denominator of Fraction B (5 x 4), find the product of numerator of Fraction B and denominator of Fraction A (1 x 12), and find the product of both denominators of Fraction A and Fraction B (12 x 4) and rewrite the equation as like the below: = (5 x 4) - (1 x 12)/(12 x 4) step 3 Simplify and rewrite the fraction: = (20 - 12)/48 = 8/48 = 1/6 5/12-1/4 = 1/6Hence, 5/12 minus 1/4 = 1/6 |
