Answer:
425+250 times 8.3%
Step-by-step explanation:
Answer: A. 0.874387438743.. is a rational number.
Step-by-step explanation:
Since Any number that can be written in fraction form is a rational number if it can be in the form of p/q where p and q are integers and q≠0
Since we can write 0.874387438743... = 
Where, 8743 and 9999 are integers and 9999≠0
Thus, 0.874387438743... is a rational number.
But, 0.0000100020003... , 5.891420975..... and 10.07401259... can not be written in the form of p/q therefore they are not the rational number.
Therefore, Only Option A is correct.
Answer:
-3 1/2 + ( -6 1/2) = -10
5/8 - {-2/8} = 7/8
- 9/10 - 2/5 = -4
6 3/5 - (-2 1/5) = 44/5
Step-by-step explanation:
-3 1/2 + ( -6 1/2) = <em>-7/2 + (-13/2) = -20/2 =</em><em><u> </u></em><em><u>-10</u></em>
5/8 - {-2/8} = <em>5/8 + 2/8 = </em><u><em>7/8</em></u>
- 9/10 - 2/5 = <em>-18-2/5 = -20/5 = </em><u><em>-4</em></u>
6 3/5 - (-2 1/5) = <em>33/5 + 11/5 = </em><em><u>44/5</u></em>
