Instead of "a half", write "eight sixteenths". That doesn't change the value of
any numbers, but it makes it a lot easier to subtract the three sixteenths from
the eight sixteenths.
85
N = 28 (you have to subtract 70 from both sides of the equation)
70
To find half of 70, you simply divide 70 by 2. This calculation gives you 35. So, half of 70 is 35.
20 can go into 70 a total of 3 times, since 20 multiplied by 3 equals 60, which is the largest multiple of 20 that is less than 70. If you subtract 60 from 70, you have a remainder of 10. Thus, 20 fits into 70 three whole times with a remainder.
28
Well, split 70 in half: 35 + 35. Add 4 (half of the 8) to one half: 39. Subtract 4 (the other half of 8) from the other half: 31. The smaller number is 31.
130
85
23 is the half of 70
The half of 140 is 70
N = 28 (you have to subtract 70 from both sides of the equation)
70 :)

To find half of 70, you simply divide 70 by 2. This calculation gives you 35. So, half of 70 is 35.
70 - (20 - 13)
20 can go into 70 a total of 3 times, since 20 multiplied by 3 equals 60, which is the largest multiple of 20 that is less than 70. If you subtract 60 from 70, you have a remainder of 10. Thus, 20 fits into 70 three whole times with a remainder.
