Question

Which of these equations is equivalent to 1 1/2 X 3 1/5 = 4 1/2?

a) 4 1/2 divided by 3 1/5 = 1 1/2

b) 1 1/2 divided by 4 1/2 = 3 1/5

c) 1 1/2 divided by 3 1/5 = 4 1/2

d) 3 1/5 divided by 4 1/2 = 1 1/2

How do you work this problem to figure this out?

Answer 1

A = 1 and 1/2 B = 3 and 1/5 C = 4 and 1/2

A*B = (1 and 1/2) * ( 3 and 1/5) = 3/2 * 16/5 = 48/10 = 24/5 = 4 and 4/5 which is NOT equal to C= 4 and 1/2

typo?

IF the statement were true, then

A is equivalent because division is the opposite of multiplication. Specifically,

A * B = C ----> C/B = A, when dividing both sides by B

A*B = C is given then A/C* B = 1 when dividing both sides by C, so B is false

C and D cannot possibly be the same statements, so they are both false...
