Because the earth is round, the distance seen on a flat map is a lot further than the distance on a globe, because of distortion. So following the circle that goes through these 3 points ( Florida, Alaska and the Philippines) it is a shorter distance to fly over Alaska.
Okay well ill do the first on and explain it so hopefully you can do the rest
3 and 1/3 is equal to 10/3 because a whole number would be 3/3 and we have 3 whole numbers plus 1/3
3/3
3/3
3/3
1/3
add it up and you get 10/3
6:$9
Multiply both by 2 (because 12/6=2)
And get 12:$18
3:7
Multiply both by 2 (because 14/7=2)
And get 6:14
6:3
Multiply both by 8 (48/6=8)
And get 48:24
Always label your units. Sorry I’m lazy
To write a mixed number as an improper fraction, first multiply the denominator by the whole number and then add the numerator.
3 × 1 = 3
3 + "numerator" = 2
5 over original denominator = 5/1
