can someone just help me

OpenStudy (michele_laino):

@coolkilla03 please note that the greatest common divisor between 45 and 120, is 15, so yuo have to divide both numerator and denominator by 15, try please

OpenStudy (michele_laino):

for example 45/15 = 3, noe do the same with the denominator, please, write your answer

OpenStudy (anonymous):

oh its 3/8

OpenStudy (michele_laino):

@coolkilla03 that's right!

OpenStudy (anonymous):

so it A

OpenStudy (michele_laino):

@coolkilla03 that's right!

OpenStudy (michele_laino):

sorry, please I have made an error, you answer is B. @coolkilla03

OpenStudy (michele_laino):

because if you multiply bot numerator and denominator of your ratio, by 2you will get: 90/120, namely D. whereas if you divide both numerator and denominator of your ratio by 5, you will get 9/24, namely C.

OpenStudy (michele_laino):

finally if you divide or multiply both numerator and denominator of your ratio by the same number, you will not never get 5/12, namely B.
