2 lbs

#### Work Step by Step

Uncooked rice equals $\frac{4}{13}$ of cooked rice. We need to make 6.5 pounds of cooked rice.You have to figure out how much-uncooked rice is needed. X equals the # of pounds of cooked rice that is needed. Thus; x=$\frac{4}{13}$ $\times$ 6.5 (change the fraction to a decimal to make it easier to multiply) x=0.31 $\times$ 6.5 x=2.015 Since you can't have 2.015 pounds you round it to 2lbs.
