Question

by what no 14/21 be multiplied so that the product is 28/81​

Answer 1

Let the number be A

A x 14/21 = 28/81

A = 28/81 x 21/14

A = 34/27

So , 34/27 should be multiplied 14/21 to get 28/81 .

Answer 2

Let's assume the number to be 'x',

so the given equation will be: 14/21 (x) = 28/81

==> x = 28/81 ÷ 14/21

==> x = 28/81 × 21/14 [reciprocal]

==> x = 14/27

∴ 14/27 is multiplied with 14/21 to get 28/81

∴ 14/27 is the required answer
