Question

-2/3×3/5+5/2-3/5×1/6​

Answer 1

Answer:

1.8

Step-by-step explanation:

-2/3×3/5+5/2-3/5×1/6​

=-2/5+5/2-3/10

=-4+25-3/10

=18/10=9/5=1.8

Answer 2

$\dfrac{-2}{3} \times \dfrac{3}{5} + \dfrac{5}{2} - \dfrac{3}{5} \times \dfrac{1}{6} =2$

Given:

• $\dfrac{-2}{3} \times \dfrac{3}{5} + \dfrac{5}{2} - \dfrac{3}{5} \times \dfrac{1}{6}$

To Find:

• Simplify

Solution

Multiplying a negative and a positive equals a negative

Step 1:

Reduce the numbers with greatest common factors

$\dfrac{-2}{1} \times \dfrac{1}{5} + \dfrac{5}{2} - \dfrac{1}{5} \times \dfrac{1}{2}$

Step 2:

Calculate the products

$\dfrac{-2}{5} + \dfrac{5}{2} - \dfrac{1}{10}$

Step 3:

Take LCM of denominators and simplify

$\dfrac{-4+25-1}{10}$

$\dfrac{20}{10}$

Step 4:

Reduce the fraction

2

Hence $\dfrac{-2}{3} \times \dfrac{3}{5} + \dfrac{5}{2} - \dfrac{3}{5} \times \dfrac{1}{6} =2$
