Question

maths
$\frac{2}{5} \times \frac{ - 3}{7} \times \frac{ - 1}{14} - \frac{3}{7} \times \frac{3}{5}$
​

Answer 1

Answer:

= -0.247

Step-by-step explanation:

= 2/5 * -3/7 * -1/14 - 3/7 * 3/5

= -6/35 * -1/14 - 9/35

= 3/305 - 9/35

= 105 - 2745 / 10675

= -2640 / 10675

= -528/2135

= -0.247

Answer 2

$( \frac{2}{5}) \: \times \: (\frac{ - 3}{7}) \: \times \: (\frac{ - 1}{14} )\: - \: (\frac{3}{7} ) \: \times \: ( \frac{3}{5} )$

_________ [ GIVEN ]

• We have to simply solve it.

_____________________________

Let's solve it by applying BODMAS Rule.

i.e.

B = Bracket

O = Of

D = Division

M = Multiplication

A = Addition

S = Subtraction

→ $( \frac{2}{5}) \: \times \: (\frac{ - 3}{7}) \: \times \: (\frac{ - 1}{14} )\: - \: (\frac{3}{7} ) \: \times \: ( \frac{3}{5} )$

→ $( \frac{ - 6}{35}) \: \times \: (\frac{ - 1}{14} )\: - \: (\frac{3}{7} ) \: \times \: ( \frac{3}{5} )$

→ $( \frac{ 6}{490}) \: - \: (\frac{3}{7} ) \: \times \: ( \frac{3}{5} )$

→ $( \frac{ 6}{490}) \: - \: (\frac{9}{35} )$

→ 0.012 - 0.257

→ - 0.245
