Answer: P(blue) total number of squares / number of blue squares
(A)
Step-by-step explanation:
42 : 24 divided by 2 is 14 : 8
14 : 8 divided by 2 is 7 : 4
The lowest form is 7 : 4
To work out do the inverse
253+326
579
Then check it by doing 579-326
=253
Y=579
1-r=-5
add r to both sides so the one side cancels out, then it should be 1=r-5
then you add -5 on each sides (because what you do to one side you must do to the other) and it would then have r on its own side which would give you your answer of r=6. To check 1-6 does equal -5
