Let x and x+2 the 2 odd consecutive numbers. Now translate from English language to Math's:
x+53 = 4(x + 2), Expand :
x+53 = 4x + 8
53 - 8 = 4x - x
45 = 3x and x = 15. So the 1st is 15 and the 2nd is 17

x=550
Hi!!
1) 2/3 *12
You basically do this
2/3 * 12/1 = 24/3 which = 8!
2) 13 * 1/2
= 13/1 * 1/2
= 13/2
= 6 1/2
Hope this helps!
