Question

11 by 12 minus 7 by 15

Answer 1

Let's see

$\\ \rm\Rrightarrow \dfrac{11}{12}-\dfrac{7}{15}$

• Take LCM (60}

$\\ \rm\Rrightarrow \dfrac{11(5)-7(4)}{60}$

$\\ \rm\Rrightarrow \dfrac{55-28}{60}$

$\\ \rm\Rrightarrow \dfrac{27}{60}$

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)
