Well since we know that for one day Mrs. Fernandez drives 6 and 1/9 miles to work what could we do to get 12 days of work driven.
all we have to do here is multiply 12 and 6 and 1/9 :) lets set this up
1 1 12
6 ---- x 12 or lets set this up like this 6 ---- x -----
9 9 1
but lets change that whole fraction into an improper fraction
1
6 ---- so all we do is multiply 6 x 9 and add the 1 so lets try that
9
6 x 9 = 54
54 +1 = 55
hey look we have our numerator!! ( the top number)
and our bottom number would stay the same as 9 so lets try this again:)
55
----- now lets plug it in to our problem
9
55 12
----- x -----
9 1
now lets just multiply across
55 12 = 55 x 12 = 660
----- x -----
<span> 9 1 = 9 x 1 = 9
</span>
so now our fraction look like this
660
-------
9
but lets make it not look so confusing and divide 660 by 9
660/9 = 73.33333333
again it still looks confusing but we can round it out to beeeee
73
so this means that for 12 days Mrs. Fernandez drove 73 miles!
hope this isnt confusing;)
have a good one and mark me brainliest!
Perpendicular to. that's what it means
