Question

find the product of 5/2×(-7/15)​

Answer 1

To solve : $(\frac{5}{2} )\times (\frac{-7}{15})$

Solution:

• Multiplication is a process of repetitive addition of integers.

• Multiplication rules for integers :

1. If two negative integers are multiplied then the product obtained is positive integer. i.e. $(-) \times(-)=+$
2. If one negative and one positive integers are multiplied then the product obtained is negative integer. i.e. $(-) \times(+)=-$
3. If both positive integers are multiplied then the product obtained is positive integer. i.e.$(+) \times(+)=+$

• Therefore according to above rule we solve.
• $(\frac{5}{2} )\times (\frac{-7}{15})$

       $= \frac{-7}{6}$

Hence, $\frac{-7}{6}$  is the product.

Answer 2
