Answer 1

SoLuTiOn:

Step-by-step explanation:

We have 2/5x-3/7-1/4-3/7 × 3/5

First we apply commutative properties, And get

2/5x-3/7-3/7 x 3/5-1/14 Now apply distributive properties and

take common -3/7, As:

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

Now solve using BODMAS properties As:

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

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

$→ - \frac{ 3}{7} - \frac{1}{14}$

Take L.C.M. of the denominator terms 7 And 14 that is 14 So

$→ - \frac{6}{14} - \frac{1}{14}$

$→ \frac{6 + 1}{14}$

$→ \frac{7}{14}$

$→ \frac{1}{2}$
