Find the difference of 5 6 - 3 4 .

Given: 5 6 - 3 4 We know that, According to the subtraction of fractions rule, For subtracting to two unlike fractions, first, change them to like fractions and then the numerators are subtracted and the denominators remain the same. So, LCM of 6 and 4 = 12 = 10 12 - 9 12 = 10 - 9 12 = 1 12 Thus, the required fraction is 1 12 .

Find the difference of 3 1 5 - 7 10 .

Given: 3 1 5 - 7 10 We know that, For subtracting two unlike fractions, first, change them to like fractions and then the numerators are subtracted and the denominators remain the same. So, convert the mixed fraction into improper fraction 16 5 - 7 10 Now, converting the unlike fraction into like fraction So, LCM of 5 and 10 = 10 = 32 10 - 7 10 = 32 - 7 10 = 25 10 = 5 2 = 2 1 2 Thus, the required difference is 2 1 2 .

Find the difference: 7 - 4 2 3

Given: 7 - 4 2 3 We know that, Accoding to the subtraction of fractions rule, For subtracting to two unlike fractions, first change them to like fractions and then the numerators are subtracted and the denominators remains same. So, convert the mixed fraction into unlike fraction = 7 1 - 14 3 = 21 - 14 3 [∵ LCM of 1 a n d 3 = 3 ] = 7 3 = 2 1 3

Find the difference: 3 3 10 - 1 7 15

Given: 3 3 10 - 1 7 15 We know that, Accoding to the subtraction of fractions rule, For subtracting to two unlike fractions, first change them to like fractions and then the numerators are subtracted and the denominators remains same. So, convert the mixed fraction into unlike fraction = 33 10 - 22 15 = 99 - 44 30 [∵ LCM of 10 a n d 15 = 30 ] = 55 30 = 11 6 = 1 5 6

Find the difference of 2 5 9 - 1 7 15 .

Given: 2 5 9 - 1 7 15 We know that, According to the subtraction of fractions rule, For subtracting two unlike fractions, first change them to like fractions and then the numerators are subtracted and the denominators remain the same. So, convert the mixed fraction into unlike fraction = 23 9 - 22 15 = 115 - 66 45 ..[LCM of 9 and 15 = 45 ] = 49 45 = 1 4 45 Thus, the required difference is 1 4 45 .

Simplify: 2 3 + 5 6 - 1 9 .

Given: 2 3 + 5 6 - 1 9 Take LCM of 3 , 6 and 9 = 18 = 12 + 15 - 2 18 = 27 - 2 18 = 25 18 = 1 7 18 Thus, the required difference is 1 7 18 .

Simplify: 8 - 4 1 2 - 2 1 4 .

Given: 8 - 4 1 2 - 2 1 4 Convert mixed fractions into unlike fractions = 8 1 - 9 2 - 9 4 So, LCM of 1 , 2 and 4 = 4 = 32 - 18 - 9 4 = 32 - 27 4 = 5 4 = 1 1 4 Thus, the required difference is 1 1 4 .

Simplify: 8 5 6 - 3 3 8 + 1 7 12 .

Given: 8 5 6 - 3 3 8 + 1 7 12 Convert mixed fractions into unlike fractions = 53 6 - 27 8 + 19 12 So, LCM of 6 , 8 and 12 = 24 = 212 - 81 + 38 24 = 250 - 81 24 = 169 24 = 7 1 24 Thus, the required answer is 7 1 24 .
