You should realize this can't be right. 11 plus 9 was 20 when I went to school. 1/8 + 1/5 is less than 1/2.
Please try again.
Is it 23 1/8 lb?
Please try again.
because the fractions add is 2/40 which reduces to 1/20? therefore making it 20 1/20 lbs????
1/5 = 8/40
5/40 + 8/40 = 13/40
Your packages weigh 20 13/40 pounds
The weight of the first package is given as 11 1/8 lbs. To add this weight, you can convert the mixed number (11 1/8) to an improper fraction. To do this, you multiply the whole number (11) by the denominator (8) and then add the numerator (1). This gives you a numerator of 89.
So, the weight of the first package as an improper fraction is 89/8 lbs.
Similarly, the weight of the second package is given as 9 1/5 lbs. Converting this to an improper fraction, you multiply the whole number (9) by the denominator (5) and then add the numerator (1). This gives you a numerator of 46.
So, the weight of the second package as an improper fraction is 46/5 lbs.
Now, to find the total weight, you add the two improper fractions:
89/8 lbs + 46/5 lbs
To add fractions, you need to have the same denominator. In this case, the lowest common multiple (LCM) of 8 and 5 is 40.
To make both fractions have a denominator of 40, you need to multiply the numerator and denominator of the first fraction by 5, and the numerator and denominator of the second fraction by 8.
(89/8) * (5/5) = 445/40 lbs
(46/5) * (8/8) = 368/40 lbs
Now, you can add the fractions:
(445/40 lbs) + (368/40 lbs) = 813/40 lbs
To simplify this fraction, you can divide the numerator (813) by the denominator (40).
813 รท 40 = 20 remainder 13
So, the total weight of the two packages is 20 13/40 lbs or, if you prefer, you can rewrite it as a mixed number: 20 1/40 lbs.
Therefore, the total weight of the two packages is not 23 1/8 lbs, but rather 20 1/40 lbs.
