Its best to turn fractions into decimals so its easier to solve the problem, in order to do this you would divide the number on the top to the number on the bottom. Ex: 1 divide by 2 So the numerator divided by the denominator. The top of the faction is the numerator and the bottom of the faction is the denominator. So 1 divided by 2 = 0.5 you would replace 0.5 for the 1/2.

Answer:
 there are 161 calories in 28 gram,then:
one gram of dry roasted cashews contains=161/28=5.75 calories
You eat 12 gram of it, =12*5.75=69 calories
9 cashews  has 12gram, then:
one gram of dry roasted cashews contains= 9/12 = 0.75 cashews
there are total of 28gram in one serving.
Therefore cashews in one serving = 0.75*28=21cashews
a)69 calories
b)21cashews
