10:47 4 track. Maria's train can go around
the track in 10 seconds. Alma's
train can go around the track in 12
seconds. David wonders, if the
trains start at the same time, how
many seconds will it take for both
trains to cross the finish line
together for the first time?
PART A
Complete the explanation for how
David can answer his question.
Use words and phrases from the
parenthesis to fill in the blanks.
(Greatest common factor, least,
multiples, factors, least common
multiple, greatest)
David needs to find the
of 10 and 12. To find this, he
could list
of both 10 and 12 and circle
each number that appears in both
lists. He should then identify the
number that is circled in both
lists,

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

i can you with this sweetie!

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
