One-fifth of a flank is sawn off and three-eights of remaining piece is then thrown away.What fraction of original remains?
Do one step at a time. First, take the 1/5 that is sawn off.
1 - 1/5 is the same as 5/5 - 1/5 = 4/5.
Next, you have to take the 3/8 away from this. Remember when adding or subtracting fractions, you must have a common denominator...in this case, it will be 40.
4/5 - 3/8 or 32/40 - 15/40 = ?
You go ahead and do the subtraction and you will have your answer.
Good luck!
To find the fraction of the original that remains after one-fifth is sawn off and three-eighths of the remaining piece is thrown away, we can break it down into steps.
Step 1: Start with the original fraction representing the whole flank, which is 1.
Step 2: One-fifth of the flank is sawn off, which means we need to subtract one-fifth from the original fraction. Subtracting fractions involves finding a common denominator. In this case, the common denominator is 5.
Step 3: Subtracting one-fifth from 1 gives us (5/5) - (1/5) = 4/5. This represents the remaining piece after one-fifth is sawn off.
Step 4: Now, three-eighths of the remaining piece is thrown away, which means we need to subtract three-eighths from the current fraction. Again, finding a common denominator is required. In this case, the common denominator is 40 (the smallest multiple of 8 and 5).
Step 5: Subtracting three-eighths from 4/5 gives us (32/40) - (3/40) = 29/40. This represents the fraction of the original flank that remains.
Therefore, after one-fifth is sawn off and three-eighths of the remaining piece is thrown away, 29/40 of the original flank remains.
