Question

12/16 - 7/18 in simplest form​

Answer 1

Answer:

The answer is $\frac{13}{36}$

Step-by-step explanation:

The formula is:

$\frac{a}{b} -  \frac{c}{d}  =  \frac{ad - bc}{bd}$

In this case :

$\frac{12}{16}  - \frac{7}{18} =  \frac{12 x 18 - 16x17}{16x18} = \frac{216 -112 }{288} = \frac{104}{288}$

To get the simples form notice both 104 and 288 are divisible by 8 and 104/8 = 13 and 288/8 = 36.

Thus $\frac{104}{288} = \frac{13}{36}$
