8/15 − 2/5 = 2/15
What is the slope of the line that passes through the points -2 15 and -8 -5?
(- 2, 15) and (- 8, - 5)m = Y2 - Y1/X2 - X1m = - 5 - 15/- 8 - (- 2)m = 10/3=======
What is two thirds of four fifths?
4/5 * 2/3 = (4*2)/(5*3) = 8/15
What is 10 and one fifth minus 4 and two thirds?
Find the lowest common denominator and convert the whole numbers to fractions, then do the subtraction and convert back to lowest terms. 10+1/5=51/5=153/15 and 4+2/3=14/3=70/15 153/15 - 70/15 = 83/15 = 5+8/15 (five and eight fifteenths)
Is 8 twelfths greater than 2 fifths?
8/12 and 2/5 can be expressed as 2/3 and 2/5. The LCM of 3 and 5 is 15. Hence 2/3 and 2/5 may be represented with the common denominator 15 as 10/15 and 6/15. Since 10/15 is greater than 6/15, 2/3 is greater than 2/5 and so the original 8/12 is greater than the original 2/5
What is 8 over 15 minus 2 over 5?
8/15 − 2/5 = 2/15
