carmen recovered 2 gold bars that were stolen from a safe. the first bar weighed 2 and 2/5 pounds. the second bar weighed 1 and 2/3 times as much as the first bar. find out how much gold was recovered.

Respuesta :

The answer would be 4 and 1/15
2 2/5 x 1 2/3 because the first bar is 2 2/5 pounds while the second bar was 1 2/3 times the first.

12/5 x 5/3   change them into improper fractions
4x1=4  weight of second bar

total gold would be 2 2/5 +4,  12/5+4= 12/5+20/5(change in common denom.)
12/5+20/5=32/5 = 5 2/5 or 6.4 pounds.
