It is: 0.75
5 plus 3 and one half equals 8 and one half. This can be calculated by first adding 5 and 3 to get 8, and then adding the additional half to arrive at 8.5. In decimal form, this is represented as 8.5.
7 plus 0.9 plus 0.03 can be written in decimal form as 7.93.
3.25
One half is 1/2, which is 0.5 written as a decimal. 3 and (plus) 0.5 is 3.5. So 3 and one half is written 3.5
4 + 210 + 5100 = 5314
1.43 m
5 + 0.4 = 5.4
5/10 plus 51/100 = 1.01 in decimal form
Write in decimal form (3 x 101) + (4 x 100)
To start with in decimal it'll be 65,910 so in standard form it would be 6.591 x 10^4
One half plus two tens can be expressed as ( \frac{1}{2} + 20 ). To combine these, it helps to express one half as a decimal, which is 0.5. Thus, 0.5 + 20 equals 20.5. Therefore, one half plus two tens equals 20.5.
That equals 0.85 of a whole, 0.50 + 0.25 + 0.10.
