Reduce (-45)/30 to the standard form....

Reduce `(-45)/30` to the standard form.

A

-9/6

B

-3/2

C

-45/30

D

-15/10

Text Solution

Verified by Experts

The correct Answer is:
B
We have, `-45/30 = (-45 div 3)/(30 div 3) = -15/10 = (-15 div 5)/(10 div 5) = -3/2`
We had to divide twice. First time by `3` and then by `5`. This could also be done as:
`-45/30 = (-45 div 15)/(30 div 15) = -3/2`
In this example, note that `15` is the `"HCF"` of `45` and `30`.
