Sure

Answer 7

the question can be interpreted as "120 is 40% of what number"
translate directly in to math
120
is means \(=\)
40% means \(.4\)
of means \(\times \)
what number, pick a variable, i pick \(x\)
\[120=.4\times x\]

Answer 8

120/40 = 3.

1% of his journey = 3 miles

100% of his journey =300 miles

Answer 9

solve via
\[120=.4x\iff x=120\div .4=1200\div4=300\]
