1+2+3+4 = 10 ---------------------- For this question there is actually a whole lot of answers... for example: ((1 + 2) + 3) + 4 = 10 ((1 × 2) × 3) + 4 = 10 (1 + 2) + (3 + 4) = 10 1 + (2 + 3) + 4 = 10 1 × (2 × 3) + 4 = 10 1 + ((2 + 3) + 4) = 10 1 × ((2 × 3) + 4) = 10 1 + (2 + (3 + 4)) = 10 ((1 + 2) + 4) + 3 = 10 (1 + 2) + (4 + 3) = 10 So Manny Diffrent way's you can use four numbers to equal 10.

1/2 of (1/10 of (3/4 of 80))) = 1/2 of (1/10 of 60)) = 1/2 of 6 = 3 Or 1/2*1/10*3/4*80 = 3
2/5 - 3/10 = (2×2)/(5×2) - 3/10 = 4/10 - 3/10 = (4-3)/10 = 1/10.
1/5 + 3/10 = 2/10 + 3/10 = 5/10 = 1/2

1 2/5 + 3/10 = 1 4/10 + 3/10 = 1 7/10

1=1 2=2 3=3 4=4 5=4+1 6=4+2 7=4+3 8=4+4 9=4+4+1 or 3+3+3 10=1+2+3+4 now 11 of course is 10 + 1 so 11=1+2+3+4+1 12 is =1+2+3+4+2 13=1+2+3+4+3 and so on 20=2*(1+2+3+4) 21 =(2*(1+2+3+4))+1 and so on and 100=(1+2+3+4)*(1+2+3+4)
2/4, 3/6, 4/8, 5/10,... To get the equivalent fractions of 1/2: Multiply 1/2 by 2/2, 3/3, 4/4, 5/5,... 1/2 * 2/2 = 2/4 1/2 * 3/3 = 3/6 1/2 * 4/4 = 4/8 1/2 * 5/5 = 5/10
