1) 2 2/5:0,4-3,7=First, convert 2 2/5 to an improper fraction:2 2/5 = (5*2 + 2)/5 = 12/5
Next, divide 12/5 by 0.4:12/5 ÷ 0.4 = (12/5) / (2/5) = 12/5 * 5/2 = 12/2 = 6
Finally, subtract 3.7 from 6:6 - 3.7 = 2.3
Therefore, 2 2/5 divided by 0.4 minus 3.7 equals 2.3.
2) 1/4 10 + 3.5 =First, multiply 1/4 by 10:1/4 10 = 10/4 = 2.5
Next, add 2.5 to 3.5:2.5 + 3.5 = 6
Therefore, 1/4 multiplied by 10 plus 3.5 equals 6.

Next, divide 12/5 by 0.4:
12/5 ÷ 0.4 = (12/5) / (2/5) = 12/5 * 5/2 = 12/2 = 6
Finally, subtract 3.7 from 6:
6 - 3.7 = 2.3
Therefore, 2 2/5 divided by 0.4 minus 3.7 equals 2.3.
2) 1/4 10 + 3.5 =
First, multiply 1/4 by 10:
1/4 10 = 10/4 = 2.5
Next, add 2.5 to 3.5:
2.5 + 3.5 = 6
Therefore, 1/4 multiplied by 10 plus 3.5 equals 6.
