8/15 − 2/5 = 2/15
(- 2, 15) and (- 8, - 5)m = Y2 - Y1/X2 - X1m = - 5 - 15/- 8 - (- 2)m = 10/3=======
4/5 * 2/3 = (4*2)/(5*3) = 8/15
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
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)
8/15 − 2/5 = 2/15
1, 2, 5, 7, 10, 14, 35, 70 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
For 70 it is: 2, 5 and 7 For 90 it is: 2, 3, 3 and 5
The median of 3, 5, 8, 15 is (5+8)/2 = 6.5
gcf(8, 18, 70) = 2 8 = 2³ 18 = 2 x 3² 70 = 2 x 5 x 7 gcf = 2
[15 - (5 + 6)]*2 = [15 - 11]*2 = 4*2 = 8
1 and 7/8 = 15/8 2 and 2/5 = 12/5 15/8 x 5/12 = 75/96 = 25/32
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.
(- 2, 15) and (- 8, - 5)m = Y2 - Y1/X2 - X1m = - 5 - 15/- 8 - (- 2)m = 10/3=======
It is: (5/3)+1 = 8/3 => 2 and 2/3 => 2.666 ..... recurring 6
lcm(7, 10, 8, 49, 70) = 1960 7 = 7 10 = 2 x 5 8 = 2^3 49 = 7^2 70 = 2 x 5 x 7 lcm = 2^3 x 5 x 7^2 = 1960
