3/10 + 3/5.
You make both denominators the same, so 3/5 is the same as 6/10.
Therefore 3/10 + 3/5 is the same as 3/10 + 6/10 = 9/10.
1/5 = 2/10Therefore 2/10 + 1/10 = 3/10
3/5 + 4/8 is the same as 3/5 + 1/2 3/5 + 1/2 is the same as 6/10 + 5/10 6/10 + 5/10 = 11/10 11/10 is the same as 1 1/10
x/2 = x/5 + 1 5x = 2x + 10 3x = 10 x = 3 1/3
-7/12 + 10/12 = 3/12 = 1/4
4/5 (4 over 5)
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
10
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
10 or 1 multiplied by ten or 5 multiplied by 2 or 3 plus7 the answer to 5 (five) plus 5 (five) is 10 (ten).
If 2 + 3 = 5 = 10(base 5), then 9 + 7 = 16 = 31(base 5).
4.825 or 433/40
Depends on what X is worth. If x was worth -10 then 5 plus - 10 = -5 so it would be lesson. But if X was worth -2, 5 plus -2 = 3.
