Remember these tips:
=> To turn a
percent into a decimal, move the decimal point 2 places to the left.
4%
means 0.04 , and 50% means 0.5 .
=> To turn a decimal into percent, move
the point 2 places to the right.
0.062 means 6.2% .
=> In
math, whenever you see the word "of", it almost always means "times".
So your 2nd example means
16 = (mystery number) x (64).
Divide each
side by 64 : 16/64 = mystery number = 1/4 = 0.25 .
Move the point 2
places to the right. 0.25 = 25% .</span>
-3b+2 will be first. -3b+2= 5b
now, 6b+2b= 8b 8b+5b= 13b 13b + 5b = 18b+2 = 20b. Idk what the last 2 is but I'm assuming add it. so. 20b is my answer..
