Question

11 by 12 minus 7 by 15

Answer 1

Let's see

`\\ \rm\Rrightarrow (11)/(12)-(7)/(15)`

• Take LCM (60}

`\\ \rm\Rrightarrow (11(5)-7(4))/(60)`

`\\ \rm\Rrightarrow (55-28)/(60)`

`\\ \rm\Rrightarrow (27)/(60)`

Answer 2

27

using bodmas rule:

`\sf b - bracket, o - order, d - division, m - multiplication, a - addtion, s - subtraction`

=================

Solve:

11 x 12 - 7 x 15 (carry out multiplication first)

132 - 105 (subtract)

27 (final answer)
