1) (4,2) - go over 4 spaces, then go up two spaces. Answer: blue triangle

2) 6:15 is equivalent to
2:5 (both 6 and 15 divided by 3)
and
18:45 (both 6 and 15 multiplied by 3)

3) 2 min 44 sec is about 2 min and 3/4 (or 0.75) of one minute. If you estimate 2.75 for each bracelet, multiply 6 bracelets by 2.75.

= 6 * 2.75
= 16.50

OR

Set up a proportion

Convert both min and sec to minutes. 2 min= 120 seconds + 44 sec= 164

x= seconds to make 6 bracelets

1 bracelet/164 sec= 6 bracelets/x
cross multiply
(1*x)= (164*6)
x= 984 seconds

Convert back to minutes/seconds
= 984 ÷ 60 seconds per minute
= 16 min 24/60 seconds
= 16 min 2/5 seconds


Answer: 16.50 is closest to 18 minutes

Hope this helps! :)
