Question

find the value of (a) 0.007+8.5+30.08 (b) 27.076+0.55+0.004 (c) 9.756-6.28 (d) 11.6-9.847 (e) 0.75+10.425+2​

Answer 1

Answer:

(a) 0.007 + 8.5 + 30.08

= 0.007 + 8.500 + 30.080

= (0 + 8 + 30) + (0.007 + 0.500 + 0.080)

= 38 + 0.587

= 38.587

(b) 27.076 + 0.55 + 0.004

= 27.076 + 0.550 + 0.004

= (27 + 0 + 0) + (0.076 + 0.550 + 0.004)

= 27 + 0.630

= 27 + 0.63

= 27.63

(c) 9.756 - 6.28

= 9.756 - 6.280

= (9 - 6) + (0.756 - 0.280)

= 3 + 0.476

= 3.476

(d) 11.6 - 9.847

= 11.600 - 9.847

= (11 - 9) + (0.600 - 0.847)

= 2 + (-0.247)

= 2 - 0.247

= 1.753

(e) 0.75 + 10.425 + 2

= 0.750 + 10.425 + 2.000

= (0 + 10 + 2) + ( 0.750 + 0.425 + 0.000)

= 12 + 1.175

= 13.175
