As we know that the decimal addition is exactly like normal addition and we don't change the position of decimal in the number.

So,

(a) $\small 0.007 + 8.5 + 30.08$

$0.007$

$8.500$

$+\:30.080$

$38.587$

(b) $\small 15 + 0.632 + 13.8$

$\small 15.000$

$\small 0.632$

$\small +\:13.800$

$\small 29.432$

(c) $\small 27.076 + 0.55 + 0.004$

$27.076$

$0.550$

$+\:0.004$

$27.630$

(d) $\small 25.65 + 9.005 + 3.7$

$25.650$

$9.005$

$+\:3.700$

$38.355$

(e) $\small 0.75 + 10.425 + 2$

$0.750$

$10.425$

$+\:2.000$

$13.175$

(f) $\small 280.69 + 25.2 + 38$

$280.69$

$25.20$

$+\:38.00$
