Question

2/5*3/7-1/14-3/7*3/5​

Answer 1

Answer:

heya mate ☺

$\frac{2}{5} \times \frac{3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5} \\ \\ = \frac{6}{35} - \frac{1}{14} - \frac{9}{35} \\ \\ = \frac{12 - 5 - 18}{70} \\ \\ = \frac{12 - 23}{70} \\ \\ = \frac{ - 11}{70}$

✌ hope it helps u ✌

Answer 2

★Given :

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

★Solution

$\frac{2}{5} \times \frac{3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5} \\ \\ = \frac{6}{35} - \frac{1}{14} - \frac{9}{35} \\ \\ = \frac{6}{35} - ( \frac{1}{14} + \frac{9}{35} ) \\ \\ = \frac{6}{35} - ( \frac{5 + 18}{70} ) \\ \\ = \frac{6}{35} - \frac{23}{70} \\ \\ = \frac{12 - 23}{70} \\ \\ = - \frac{11}{70}$

★Explanation :

Formula used here : "BODMAS"

B = BRACKET

O = OF

D = DIVISION

M = MULTIPLICATION

A = ADDITION

S = SUBSTRACTION

• First of all, as there's no function of Bracket and Of so the division would be done at first.
• Then respectively the multiplication, addition and substraction would be done.
• Applying this formula we get the answer.
