Ah, what a happy little question! The inverse operation of multiplication is division, so to find the inverse of 3x5 equals 15, you would divide 15 by 5 to get 3. Remember, math is like painting a beautiful landscape - just follow the steps with a gentle touch and you'll create something wonderful.
Commutivity of multiplication or the commutative property of multiplication.
1x15 3x5 5x3 15x1
All of them. 1x15,2x7.5, 3x5, 4x3.75, 5x3...
since 15 = 3x5 and 75 = 3x5x5 H.C.F = 5X3 = 15 !
7
3x5
95
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
seventeen over fifteen because the common denominator of 5 and 3 is 15 think about it like this: 4/5x3, 4x3=12, 5x3=15 1/3x5, 1x5=5, 3x5=15 so you get 12/15+5/15 see how they simplify back? then add the numerators and keep the denominator and you get 17/15 or 1 and 2/15
5+5+5
If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
