65/8 = 1625/200
7/25 = 56/200
1681/200 = 8 and 81/200
As written, that is true. (7 - 1) + 8 = 7 - (1 + 8) is not true.
2/3 plus 3/8 is equal to 25/24.
25
It is: 8+1+7 = 16

percent means out of 100 → 25% of 7/8 = 25/100 × 7/8 = (25×7)/(100×8) = 175/800 = (7×25)/(32×25) = 7/38 It would have been prudent to simplify the 25% before the multiplication: 25% of 7/8 = 25/100 × 7/8 = (1×25)/(4×25) × 7/8 = 1/4 × 7/8 = (1×7)/(4×8) = 7/32 But then again, it is expected that students should recognise 25% as ¼
8 + 9 + 7 + 1 + 11111 = 11136
8
36 + 4 - 8 -7 = 25
1 + 1 + 6 = 8
-7+8=1
