Given a number 5/48 Let the other be x Given that the product = -15/56 ⇒ 5/48 × x = -15/56 ⇒ x = -15/56 ÷ 5/48 ⇒ x = -15/56 × 48/5 ⇒ x = -720/280 ⇒ x = -18/7 ∴ The other number is -18/7

Let the other be x
Given that the product = -15/56
⇒ 5/48 × x = -15/56
⇒ x = -15/56 ÷ 5/48
⇒ x = -15/56 × 48/5
⇒ x = -720/280
⇒ x = -18/7
∴ The other number is -18/7
