How do you divide fractions without reciprocals?
Using reciprocals, a/b divided by c/d is the same as a/b times d/c. If you multiply this, you get ad/bc.Without thinking about this as reciprocals, you can do this multiplication directly, cross-multiplication so to speak.
Find the sum of the reciprocals of two real numbers given that these numbers have a sum of 150 and a product of 40?
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
Two numbers whose product is 1 are called?
Two numbers with a product of 1 are called reciprocals. If you have a number and want to find the reciprocal of it, simply divide 1 by the number. For example, the reciprocal of 5 is 1/5, and the reciprocal of 700 is 1/700.
Why you take reciprocals of intercepts for finding miller indices?
Using reciprocals spares us the complication of infinite intercepts.Formulas involving Miller indices are very similar to related formulas from analytical geometry.
What is the reciprocal of the sum of the reciprocals of 6 and 8 and how did solve?
Well, honey, the reciprocal of a number is just 1 divided by that number. So, the reciprocals of 6 and 8 are 1/6 and 1/8. Add those bad boys up, you get 7/24. Flip that sum upside down and you've got yourself the reciprocal of the sum of the reciprocals of 6 and 8, which is 24/7. Math can be a real rollercoaster, but we're just along for the ride!
