ASSESSMENT : 3 Class : VII MATHEMATICS 15 Q.1 The product of two numbers is -5/6. If one number is 15/12, find the other.​

Answer 1

Answer is -2/3

Step-by-step explanation:

x × 15/12 = -5/6

x = -5/6 ÷ 15/12

= -5/6 × 12/15

= -2/3

Answer 2

Answer:

Given :

• The product of two numbers is - 5/6.
• One number is 15/12.

To Find :-

• What is the other number.

Solution :-

Let,

$\mapsto \bf Other\: Number =\: x$

According to the question,

$\implies \sf \dfrac{- 5}{6} =\: \dfrac{15}{12} \times x$

$\implies \sf \dfrac{\dfrac{- 5}{6}}{\dfrac{15}{12}} =\: x$

$\implies \sf \dfrac{- 5}{\cancel{6}} \times \dfrac{\cancel{12}}{15} =\: x$

$\implies \sf \dfrac{- \cancel{5}}{1} \times \dfrac{2}{\cancel{15}} =\: x$

$\implies \sf \dfrac{- 1}{1} \times \dfrac{2}{3} =\: x$

$\implies \sf \dfrac{- 1 \times 2}{1 \times 3} =\: x$

$\implies \sf \dfrac{- 2}{3} =\: x$

$\implies \sf\bold{\red{x =\: \dfrac{- 2}{3}}}$

${\small{\bold{\underline{\therefore\: The\: other\: number\: is\: \dfrac{- 2}{3}\: .}}}}$
