### Vanessa's BOB 2 on ratios

Heeey sorry about my late post for BOB2 on ratios but here it is ....

What were some mistakes you did on your tests ?
A mistake that I did on my tests is that i didn't simplify it ( lowest terms ). Another mistake I did on my tests is not showing enough work, so I got less than what i should have gotten.
What I can do to improve my future tests...
I can study hard and read the questions slowly.

Questions...

1) A picture frame has a width to length ratio of 5:7 . If the width of the photo is 9cm, the length of the photo is ?
a) 11cm b) 12.6cm c) 14cm d) 16cm

The other question is just simplifying the ratio.
