Question

If you add 1/3 from a number and multiply by result by 1/8 you get 1/4​

Answer 1

Answer:

10\6

Step-by-step explanation:

let the number = k

according to question

1\3+k(1\8) = 1\4

1+3k\3 ( 1\8) = 1\4

1+3k\24 = 1\4

12k + 4 = 24 ( by cross multiplication)

12k = 20

k = 20\12

k = 10\6

Answer 2

Step-by-step explanation:

An equation is a mathematical statement with an 'equal to' symbol between two algebraic expressions that have equal values.

Let's form a linear equation for the given problem statement.

Given,

1/2 is subtracted from a number

Result is multiplied by 1/2

Answer is 1/8

Let the number be x

Following the steps given in the question,

(i) x - 1/2

(ii) 1/2 × (x - 1/2) = 1/8

Solving the above equation,

1/2 x - 1/4 = 1/8

⇒ 1/2 x = 1/8 + 1/4

⇒ x = 2(1 + 2)/8

⇒ x = 3/4

Thus, the number is 3/4
