\(\color{#0cbb34}{\text{Originally Posted by}}\) @LARENZIE 1.4 inches is cut off each board Explanation: We have a mixture of units. It is much easier to make a comparison if all measurement use the same units. I choose inches 1 board is 8 ft. Each foot has 12 inches in it. So they are 8 × 12 inches long. This is 96 inches. The boards are cut to 94.6 inches long. The amount wasted is 96.0 − 94.6 Write as: 96.0 94.6 −−−− There is a zero above the 6 so lets make this easier to work out Move the value of 1 from the 96 into the tenths so we have 96 is the same as 95 + 10 10 → 95 . 0 10 95 . 0 10 94 . . . 6 −−−−−− ← Subtract 9 1 . 00 4 So the amount of waste is 1.4 inches This is the same as 1 4 10 → 1 2 5 inches srry that I didn't explain it \(\color{#0cbb34}{\text{End of Quote}}\) https://socratic.org/questions/sandy-is-working-with-a-carpenter-to-frame-a-house-they-are-using-8-foot-long-bo There’s the source they got it from too
