solve the equality 12x + 64 is less than or equal to 239

i got 14.5 and we have to round down to the nearest whole number i have to give my answer as an inequality. How would that look

12x + 64 ≤ 239

subtracting 64 ... 12x ≤ 175

dividing by 12 ... x ≤ 14 7/12

rounding down ... x ≤ 14

FYI... usually, fractions greater than 1/2 are rounded up
