Question

subtract 3 by 4 from 5 by 6​

Answer 1

Given :  Subtract 3/4 from 5/6

To Find : Evaluate

Solution:

Subtract 3/4 from 5/6

5/6   - 3/4

Take LCM of Denominators 6 and 4

6 = 2 * 3

4 = 2 * 2

LCM = 2 * 2 * 3 = 12

LCM  - Least common multiplier of given numbers is the least number which is perfectly divisible by given numbers.

LCM = product of each factor  of highest power

create equivalent fractions :

By dividing or multiplying the numerator and denominator of a given fraction by the same number except zero

a/ b  = ak/bk      k ≠ 0

a/b  = (a/k) / (b/k)   k ≠ 0

5/6  = 5 * 2/ (6 * 2)  = 10/12

3/4  = (3 * 3) /( 4 * 3) = 9/12

5/6 - 3/4

= 10/12 - 9/12

= (10 - 9)/12

= 1/12

Hence 5/6   - 3/4 = 1/12

Answer 2

Answer:

$=> \frac{1}{12}$

Step-by-step explanation:

Given that:-

$\frac{5}{6}-\frac{3}{4}$

To find:- The value of the expression,

For solving, we have to use the BODMAS method:

where,  

      B= bracket    

      O= order of power or rules      

      D= division    

      M= multiplication    

      A= addition    

      S= subtraction  

As we have,

=> $\frac{5}{6}-\frac{3}{4}$

First of all, we have to find the LCM:

=> $\frac{5\times 2}{6\times 2}+\frac{-3\times 3}{4\times 3}$

By simplifying it further, we get

=> $\frac{10}{12}+\frac{-9}{12}$

Combine the fractions,

=> $\frac{10+-9}{12}$

Add the terms in the numerator,

$=> \frac{1}{12}$

Hence, the required solution is $\frac{1}{12} .$
