Question

$(3\times \frac{1}{4} + 1 \times \frac{2}{7} -\frac{17}{28} ) \times 1 \times \frac{15}{41}$

Answer 1

(3x1/4+1x2/7-17/28)x1x15/41
(3x1/4+2/7+17/28)x15/41
(2/4+2/7+17/28)x15/41
(14/28+14/28+17/28)x15/41
(28/28+28/28)x15/41
56/28x15/41
=130/88

Answer 2

   (3 x 1/4 + 1 x 2/7 - 17/28) x 1 x 15/41 = 
= (3/4 + 2/7 - 17/28) x 15/41 = 
= (21/28 + 8/28 - 17/28) x 15/41 = 
= 12/28 x 15/41 =
= 3/7 x 15/41 = 
= 45/287
