Each answer is ( - 1 ) times the other answer.
9/7 is the reciprocal of 7/9.9/7
Identify the property illustrated 7 + 9 = 9 =7
79/98 7/9:= [(9 *8)+7]/9= [72+7]/9= 79/9 in improper fraction
if 7 cost 1.40 then 7÷7 = 1 cost 1.40 ÷ 7 → 1×9 = 9 cost (1.40÷7) × 9 = 1.80 9 will cost 1.80
The significant relationship between 3, 4, and 7 is that 3+4=7.
To find the ratio between 9 and 7, you simply divide one number by the other. This can be expressed as 9:7, which means for every 9 parts of one quantity, there are 7 parts of another. Alternatively, you can also represent it as a fraction: 9/7. This indicates that 9 is greater than 7, and the ratio reflects that relationship.
(-9) / (-7) * 7 = 9/7*7 = 9
It is because of the way integers are defined. There is a binary relationship, "less than", defined for integers which requires that 7 < 8 and 8 < 9. This relationship is transitive and so the two parts can be combined to give 7 < 8 < 9 as required.
It is (9 + 9 + 7 + 7)/4 = 8

(7/9) / (9/10) = (7/9) * (9/10) = 7/10 = 0.7
-9
2 |9| is 9 and |7| is 7 so 9-7 is 2
63
2 |9| is 9 and |7| is 7 so 9-7 is 2
9/7 is the reciprocal of 7/9.9/7
It is 7 lots of 9 = 7*9 = 63.
