Which number is half way between each of these pairs 3/20 and 7/10 ths?
Answers:
17/40
17/40ths
You need to state these fractions with the same denominator, i.e 3/20 and 14/20. Then find mean of 3 and 14 =17/2, so (17/2)/20 is the answer = 17/40
Add them and divide by 2
3/20 + 7/10 = 3/20 + 14/20 = 17/20
(17/20)/2 = (17/20)(1/2) = 17/40
Well lets do this out,
you would say
=(3/20 + 7/10)/2
=(3/20 + 14/20)/2
=(17/20)/2
=17/40
Find the common denominator:
3/20 is the same as 6/40
7/10 is the same as 14/20 is the same as 28/40
Halfway between 6 and 28 is (28-6)/2, or 11, so add 11 to 6 to get
17/40
half way between 3/20ths and 710ths
=(6+28)/(40*2)
=34/80
17/40ths
i hope that this helps
Yes, it is 17/40. I worked it out wrong at first but now I agree it is 17/40
3/20 + 14/20 / 2 = 17/20 /2 = 17/40
if you need a real number its 42.5
Turn 7/10 into 20th's, so that's 14/20. Now they've got a common denominator. Add 3/20 to 14/20 and you get 17/20. But to find out the number betwen the two of them, divide 17/20 by 2. When you divide a fraction by something else you flip the number you're dividing by over and multiply it instead. So instead of 17/20 divided by 2/1, you get 17/20 multiplied by 1/2. Multiply numerators, multiply denominators, and this is what you get:
17/40. And this is your answer.
(3/20 + 14/20)/2= 17/40
