Question

divide the difference of 1/3 and 1/5 by the sum of 1/2 and 1/5

Answer 1

Given,

The terms for division are, difference of ⅓ and ⅕ ; sum of ½ and ⅕

To find,

The result of division of the given terms.

Solution,

We need to calculate the final numerical value of the given terms in order to simplify the division.

The first term = difference of ⅓ and ⅕ = ⅓ - ⅕ = (5-3)/15 = 2/15

The second term = sum of ½ and ⅕ = ½ + ⅕ = (5+2)/10 = 7/10

So,the division = First term / Second term = 2/15 ÷ 7/10 = 2/15 × 10/7 = 2/3 × 2/7 = 4/21

Hence,the result of division of the given terms is 4/21
