2/10 + 3/4 = 4/20 + 15/20 = 19/20
-2 + 10 - 8 + 4 - 3 + 2 = 3
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
10
1+2+3+4=10
11 + 7 + 5 + 4 + 3 + 3 + 3 + 2 + 2 + 2 = ?First, group things in groups of tens (or twenties).(11 + 5 + 4) + (7 + 3) + (3 + 3 + 2 + 2) + 2 = ?20 + 10 + 10 + 2 = ?30 + 12 = ?42 = ?So your answer is 42.
It's 10. 3 times 2 is 6, 6 plus 4 is 10, and 10 times 1 is 10.
25+20+10+5+4+3+2=69Math:25+20=45 | 25+20+10+5+4+3+245+10=55 | 25+20+10+5+4+3+255+5=60 | 25+20+10+5+4+3+260+4=64 | 25+20+10+5+4+3+23+2=5 | 25+20+10+5+4+3+264+5=69
2/5 + 3/10 =4/10 + 3/10 =7/10
(10+9)+(1−1)+(2−2)+(3−1)+(4−4) = 21This is the same equation rewritten: (10+9)+(3−1) = 21This can be done as 1-1, 2-2, 4-4 cancel themselves out.
2/3 + 3/4 + 10/12 = 8/12 + 9/12 + 10/12 = 27/12 = 2 & 3/12 = 2 & 1/4
the answer is simply 2 because 10+-3 is 7+-4 is 2 you just subtract negatives from the positives
4-5+6+2-10= -3
