Question

Subtract 3/4 from 5/6

Answer 1

Answer:

1 /12

Step-by-step explanation:

LCM of the two denominators:

LCM of 6 and 4 is 12

For the 1st fraction, since 6 × 2 = 12,

5 /6  =  5 × 2 /6 × 2  =  10 /12

Likewise, for the 2nd fraction, since 4 × 3 = 12,

3 /4  =  3 × 3 /4 × 3  =  9 /12

Subtract the two fractions:

10/12  -  9/12  =  10 - 9 /12  =  1 /12

Answer 2

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
