It is 2.25
Well, what is half of 36? 18. Now what is half of 18? 9.9
By repeated subtraction. For example 21 divided by 2 : you can take away 2 ten times and you are left with a half of two, so answer ten and a half. They probably assembled tables of divisions.
Well, isn't that an interesting question! If you started with ten dollars and gave away all but three dollars, you would have three dollars left. It's important to remember that it's not about how much you have, but how you appreciate and make the most of what you do have.
one take away one tenth = nine tenths
3/4 - 2.5 Two methods #1 ; convert both numbers to decimals. Hence 3/4 = 0.75 0.75 - 2.5 = -1.75 or #2 ;convert to both number to fractions. 3/4 - 2 1/2 3/4 - 5/2 = 3/4 - 10/4 = -7/4 = 1 3/4 Remember -1 3/4 = -1/75
it is just one quarter
one half
Three eights. There are four eights in one half.
do you own a calculator? so 1.5 is half of 3, so you multiply 3 by two, and take away half of three: 4.5
Yes, half of a circle made of eights is 4 eights. Take away 3 eight you still have 1 left.
50. First you have to find out what a quarter of 400 is before you can take half of that number. So one quarter of 400 is the same as dividing by 4, so the answer is 100. Then you'll need to take half of that number, which is 50.
Twenty-eight and one eighth.
