Question

George is on the high school wrestling team and he has to be careful to stay in his weight class .he is in the sixth life weight class which includes wrestlers who wait between 138 and 145 pounds George weighed 138 and 1/2 lb for Christmas But gained 3 and 3/5 lb from eating too much holiday food what is maximum amount of weight George can gain before to move up to the next weight class

Answer 1

hello

to solve this question, we need to add up the weight he gained during christmas t his previous weight and then see if it meets the range of his weight class

convert the mixed fractions to improper fractions. This is done to ease up our calculation

previous weight=

`138(1)/(2)=(277)/(2)`

added weight =

`3(3)/(5)=(18)/(5)`

new weight = previous weight + added weight

new weight =

`(277)/(2)+(18)/(5)=(1421)/(10)=142.1`

George's new weight is 142.1 lb and this is still within the range of his weight class.

the quantity of pound left for George to move up to the next weight class is

quantity left = 146 - his new weight

quantity left =

`146-142.1=3.9lb`

from the calculations above, George needs to add 3.9lb to move up to the next weight class.
