Question

(6 2/5 * 2 11/12 - 16) * 2 1/4
(6 - 2 1/10 * 2 1/7) * 4/15
(1 7/8x - 2 1/3) x 24

Answer 1

(6 2/5 * 2 11/12 - 16) * 2 1/4=15

6 2/5*2 11/12=32/5*35/12=28/3=9 1/3

9 1/3-16=6 2/3

6 2/3*2 1/4=20/3*9/4=15

(6 - 2 1/10 * 2 1/7) * 4/15=1 1/5

2 1/10*2 1/7=21/10*15/7=9/2

9/2*4/15=6/5=1 1/5

(1 7/8x - 2 1/3) x 24=(15/8х-7/3)*24=45х-56
