Answer:
If fraction is sold, then it is 7.5
If they sell no fractions, least amount would be 8
Step-by-step explanation:
In this question, we are trying to calculate the least amount of a particular length of wood that would be enough to make a particular number of dowels.
Firstly, we should notice we have a unit problem. This is the sense that the metric units are not the same all over. Let’s calculate the total length of dowels he has to make. That will be 6 inches * 60 = 360 inches length.
Now, we need to know the amount of wood that is to be bought. The wood comes in 4-foot length. If we recall, 12 inches makes one foot. This means the length of wood she is to buy would be 12 * 4 = 48 inches length of wood.
Now to know the meat number of wood of 4-inches length she is to buy, what we do is to divide 360 by 48 = 360/48 = 7.5.
Hence, the least number of 4-length wood she is to buy is 7.5
Note: if they won’t sell a fraction, then the least amount to be bought would be 8
