Once because 7 - 49 = -42 but you can subtract 7 from 49 seven times
From the first term subtract 19 to get the second, and continue to subtract the next smaller odd number to proceed down the line:100 (-19) 81 (-17) 64 (-15) 49 (-13) 36 (-11) 25 (-9) 16
68
21
9
Subtract a negative 1. 19 - (-1) = 20
30 + 19 = 49
49 x 19 = 931
19
To find the number you need to subtract from 49/6 to get 8, you can set up the equation as follows: 49/6 - x = 8. To solve for x, you would first convert 8 to a fraction with a denominator of 6, which is 48/6. Then, subtract 48/6 from 49/6 to get 1/6. Therefore, you would subtract 1/6 from 49/6 to get 8.
"negative 49 over 19" is the ratio of -49 to 19. That's rational.
7 can be subtracted from 49 only one time.
