1 and 1/2
5/10 - 4/10 = 1/10
Convert the two elements to tenths, which gives 8 tenths subtract 5 tenths, leaving the answer as 3 tenths.
two and one half
The answer is 1/4. There are 4 fourths in a whole. Convert 1/2 into 2/4, then subtract 1/4
5 - 2.5 = 2.5
1.25 - 0.50 = 0.75 ■
3/4 - 1/2 = 3/4 - 2/4 = 1/4
6 and 1/4
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.
2+2-8=-4
4.
Subtract two times the length from the perimeter and cut that answer in half.
