pleeeaaaaaaassssssseeeeee help with this for brainlist and 5 stars

1.A) Any number x multiplied by [tex]\frac{1}{2}[/tex] will be less than the original x.
1.B)
[tex]\frac{4}{4}[/tex] = 1, so B
[tex]\frac{6}{4}[/tex] = 1.5, so F
The rest are similar.
2) There are 4 quarts in a gallon, so calculate the number for 2 gallons.
3) 4 ÷ [tex]\frac{1}{6}[/tex] is the same as 4 × 6
4) Follow PEMDAS rules, Parenthesis first, division and multiplication next, then finally addition.
