Question

Someone please explain number four thanks

Answer 1

1/5 of 3 ..
=> 1/5 * 3 is same as 3 * 1/5 ..
=> 1/5*3 = 3/5 and 3* 1/5 also = 3/5 ...
  here the commutative property of multiplication is used ... which tells us that it doesn't matter in what order you multiply numbers. The formula for this property is a * b = b * a. .... so if we know these properties it will be easy to figure out the answer ...


hope it helps !!!!
