Answer 1

2/7 =0.2857

Explanation:

0.9(300/225-1/8(1x3+2/3+1/9))-4/7/0.8

0.9(4/3-1/8(1x3+2/3+1/9))-4/7/0.8

0.9(4/3-1/8(3+2/3+1/9))-4/7/0.8

0.9(4/3-1/8(5/3+1/9))-4/7/0.8

0.9(4/3-1/8(15/9+1/9))-4/7/0.8

0.9(4/3-1/8x(15+1/9))-4/7/0.8

0.9(4/3-1/8x(16/9))-4/7/0.8

0.9(4/3-1x16/8x9))4/7/0.8

0.9(4.3-16/72)-4/7/0.8

0.9(4/3-2/9)-4/7/0.8

0.9(12/9-2/9)-4/7/0.8

0.9x(12-9/9)-4/7/0.8

0.9x(10/9)-4/7/0.8

9/10x(10/9)-4/7/0.8

1-4/7/0.8

1-4/7x0.8

1-4.56

1-40/56

1-5/7

7/7-5/7

7-5/7

2/7 = 0.2857

Answer 2

2/7.

Explanation:

Using order of operations (PEMDAS):

0.9 (3 / 2.25 - 1/8( 1 2/3 + 1/9)) - 4/7 / 0.8

= 0.9 (3 / 2.25 - 1/8( 5/3 + 1/9)) - 4/7 / 0.8

= 0.9 (3 / 2.25 - 1/8( 16/9) - 4/7 / 0.8

= 0.9 (3 / 2.25 - 2/9) - 4/7 / 0.8

= 0.9 (12/9 - 2/9) - 4/7 / 0.8

= 0.9 * 10/9 - 5/7

= 1 - 5/7

= 2/7.
