Math problems in the sixth grade (solving equations)
X is: the first:1.8-4/15 = 27/15-4/15 = 23/15 =1and 8//kloc.

Second: 61/40-1.375 = 61/40-55/40 = 6/40 = 3/20.

The third one: 7.2-5 2/3 = 36/5-17/3 =108/15-85/15 = 23/15 =/kloc-.

Fourth: 2 and11/20+10.75 = 51/20+43/4 = 266/20 =133/10 =

Fifth; 6 5/8- 1 1/ 12 = 53/8- 1 1/ 12 = 159/24-22/24 = 138.

Sixth: 2 plus 25 minus1.82 = 58/25-91/50 =16/50-91/50 =1/2,

Then; X= 1/2+3 and five sevenths =1/2+26/7 = 7/14+52/14 = 59/14 = 4 and 3//kloc. .

I have been calling for a long time. I hope it helps you. . .
