Answer 2

Given:

$(a) 5/ 4 \times -1/ 15\\(b) 8/9 \div2$

We have to evaluate the above equation.

• As we know that the multiplication is a method to get the product by multiplying two or more values.
• Multiplication is denoted by the symbol(x).
• And the division is one of the basic operations of arithmetic, the ways that numbers are combined to make new numbers.
• The division is denoted by a sign$(\div)$.

We are solving in the following way:

We have,

$(a) 5/ 4 \times -1/ 15\\(b) 8/9 \div2$

$(a) 5/ 4 \times -1/ 15\\\\\Rightarrow \frac{5}{4} \times \frac{-1}{15} \\\\\Rightarrow \frac{-5}{90} \\\\\Rightarrow \frac{-1}{12}$

$(b) 8/9 \div2\\\\\Rightarrow \frac{8}{9} \times \frac{1}{2} \\\\\Rightarrow \frac{8}{18}$

Solving the above equation further we get,

$\Rightarrow \frac{4}{9}$

Hence, we get,

$a)\ \frac{-1}{12} \\\\b) \ \frac{4}{9}$
