0.045*0.5*0.8
= 0.045*0.4
= 0.018
98.1-7.7/0.7*5.8
= 98.1-11*5.8
= 98.1 - 63.8
= 34.3
0.8*(5.2-2.99/2.3)
= 0.8*(5.2- 1.3)
= 0.8*3.9
= 0.8 * (4-0.1)
= 3.2 -0.08
= 3.12
9.6/(3.94+0.86)*0.8
=9.6/4.8*0.8
=2*0.8
=1.6
= 0.045*0.4
= 0.018
98.1-7.7/0.7*5.8
= 98.1-11*5.8
= 98.1 - 63.8
= 34.3
0.8*(5.2-2.99/2.3)
= 0.8*(5.2- 1.3)
= 0.8*3.9
= 0.8 * (4-0.1)
= 3.2 -0.08
= 3.12
9.6/(3.94+0.86)*0.8
=9.6/4.8*0.8
=2*0.8
=1.6
