subtract 4 from 1/6 of 42

1 sixth is [tex] \boxed{\frac{1}{6}} [/tex]
1 sixth of 42 is [tex] \boxed{\frac{1}{6} \times 42} [/tex] or [tex] \boxed{\frac{1}{6}} [/tex] multiply 42.

Let us write an expression to match for subtract 4 from [tex]\frac{1}{6}[/tex] of 42.

[tex]\boxed{\boxed{ \ \bigg(\frac{1}{6} \times 42 \bigg) - 4 \ }}[/tex]

And now we evaluate the expression.

[tex]\boxed{ \ = \bigg(\frac{1}{6} \times 42 \bigg) - 4 \ }[/tex]

We cross out 6 and 42 because they both can be divided.

[tex]\boxed{ \ = 7 - 4 \ }[/tex]

Thus the answer is [tex]\boxed{\boxed{ \ 3 \ }}[/tex]

Notes:

Recall that [tex]\boxed{\frac{42}{6} \rightarrow 42 \div 6 = 7}[/tex]
Since [tex]\boxed{ \ \boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 42 \ }[/tex], then one of six parts of 42 or [tex]\boxed{\frac{1}{6} \ of \ 42 \ equal \ to \ 7}[/tex]
Since [tex]\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1}\boxed{1} = 7[/tex], then subtract 4 from 7 equal to 3, that is [tex]\boxed{1}\boxed{1}\boxed{1} = 3[/tex].
