0.98*302
=0.98*(300+2)
=0.98*300+0.98*2
=294+1.76
=295.76
25*4.4*0.7
=(25*4)*(1.1*0.7)
=100*0.77
=77
5.8*5.8+5.8*0.5+5.8
=(5.8+0.5+1)*5.8
=7.3*5.8
=42.34
(0.25*12.5)*(4*0.8)
=(0.25*4)*(12.5*0.8)
=1*10
=10

3.5-7 2 / 9 + 6 1 / 2 (simple calculation)

3.5-7 and 2 / 9 + 6 and 1 / 2
=3.5 + 6 and 1 / 2-7 and 2 / 9
=10-7 and 2 / 9
=9 and 9-7 and 2-9
==Two and seven ninths

Recursive equation calculation: 65 times 2 / 5 + 65 times 3 / 5 75 divided by 8 / 9 minus 35 times 4 / 5 5 / 12 + (5 / 6 minus 1 / 12) divided by 9 / 16
Hurry, please

65 times 2 / 5 + 65 times 3 / 5 = 65x (2 / 5 + 3 / 5) = 65x1 = 6575 divided by 8 / 9 minus 35 times 4 / 5 = 75x9 / 8-28 = 72x9 / 8 + 3x9 / 8-28 = 81-28 + 37 / 8 = 63 + 3 and 3 / 8 = 66 and 3 / 85 / 12 + (5 / 6 minus 1 / 12) divided by 9 / 16 = 5 / 12 + 9 / 12x16 / 9 = 5 / 12 + 16 / 12 = 21 / 12 = 7 / 4. I hope you like this kind of calculation
