What number will go into 10 and 12?
There are 2 numbers that go into both 10 and 12. They are 1 and 2.
What number can go into both 5 and 12?
It is: 1
What number does 9 and 12 go into?
9 and 12 can both go into multiples of their least common multiple, which is 36. Therefore, 36 is the smallest number that both 9 and 12 can evenly divide into.
What number gose into 10 and 5?
5 and 1 both go into 10 and 5.
12 and 5 6ths minus 8and one fourth?
12 and 5/6 - 8 and 1/4 To solve this problem, subtract the whole numbers first. 12 - 8 = 4. Now we can work on the nasty little fractions! 5/6 - 1/4. In order to add or subtract fractions, we need to have a common denominator, that is, the same number on the bottom of BOTH fractions. 6 and 4 aren't the same, so we'll need to multiply and find a number that is the same. Are there any numbers both 6 and 4 can go into evenly? Don't pick a large number, start small. Well, 6 can go into 12 evenly. and 4 can also go into 12 evenly! OK, how many times does 6 go into 12? 2 times. We need to multiply 5/6 * 2/2 to get a 12 on the bottom. 5/6 * 2/2 = 10/12 (try reducing this fraction, see if 10/12 = 5/6) How many times will 4 go into 12? 3 times, that's right. Now multiply 1/4 * 3/3 = 3/12 (reduce 3/12 to lowest terms to check) So, since 5/6 = 10/12 and 1/4 = 3/12 --> 10/12 - 3/12 When adding or subtraction fractions, the bottom has to be the same. (Check!) Add or subtract fraction top numbers ONLY! Keep the same bottom number. 10/12 - 3/12 = 7/12. Combine this with the whole number we calculated earlier and we get: 12 and 5/6 - 8 and 1/4 = 4 and 7/12
