answer: b over a
for ur question:
if, a/b = 3/4
then, 4/3 = ?
when u switch the place holders like that, it is called the 'inverse'. and since 4/3 is the inverse of 3/4, then the inverse of a/b is b/a.
4/b-3 + 3/b = -2b/b-3 b = 1 or b = -4.5
2*3*4 = 24
It is: a/3 times b/4 = ab/12
8/9
first you add 2 to the 8. the 2 crosses out itself so now you have b over 4 equals 10. then you multiply the 4 to the ten and the 4 the 4 crosses out itself and you end up with b= 40
a and b both have the probability of 3/4
1 is the answer. -(-4)- 3 = 4-3 = 1 .
3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b
If: b/5+b/3 = 10 then b works out as 18.75
It is difficult to answer the question because it is still ambiguous. Putting brackets in helps. So: (3 over 4) x b = 3/4*b = 3*b / 4 YES but 3 over (4 x b) = 3/(4*b) is not 3/4*b
4/b-3 + 3/b = -2b/b-3 b = 1 or b = -4.5
Only one: 3.
2*3*4 = 24
It is: a/3 times b/4 = ab/12
8/9
(b/12)=(2/3) b=(2/3)*12 b=8 so, (8/12)=(2/3) 0.6667=0.6667
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators
