2 over 7 = 2/72/7 = 0.285714 in decimal
2/5, 2+7=9
2 2/7 (mixed). 16/7 is already improper.
Their highest common factor is 7. Dividing both numbers by 7, gives you 2 over 27.
They are 1/7 and 2/14
Divide both numbers by 2 and you will get 7 over 34.7/34
-7/3 - -2/3= -7/3 + -2/3 I am not going to do this for you. But since you have a common denominator, all you really have to do is add the top numbers.
the reciprocal of 1 over 2, is 2. reciprocal just means you flip the numbers over, in this case it leaves 2 over 1 which is the same as 2 divided by 1 which is 2. for example the reciprocal of 10 is 1 over 10 and the reciprocal over 1 over 7 is 7.
If you mean 3/8 and 7/8 then they are 1/4 and 1/2.
When you divide a fraction by a fraction, you have to multiply the first number by the reciprocal of the second.2/7 divided by 5/92/7 multiplied by 9/5Then you multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together to give you the final answer.2 x 9 and 7 x 5= 18/35
2 over 7 + 3 over 7= 5 over 7
The pattern is multiply by -1, add 5, repeat. The next three numbers are: -7, -2, 2
negative 2 over 7
