Good work @lawson4238

anonymous · Answer

as 6 : 10 = 6/10 = 6*4/10*4 = 24/40 

So it must be 24/40 and NOT 24/45 and hence you are right with the option D)

anonymous · Answer

ye so u jus reduce to the lowest terms to find out if it equal

anonymous · Answer

Yes like this :

$$\large{\frac{24}{45} = \frac{3*8}{3*15} = \frac{\cancel{3}^1 * 8 }{\cancel{3}^1 * 15} = \frac{8}{15} = \textbf{HCF of 8 and 15 is 1} }$$

Therefore 8/15 is the most simplified form of 24/45 and therefore, 24/45 is not equal to 6/10
