Grant has 2/3 cup of ice cream in a bowl. He then removes two 1/6 cups of ice cream to share with his little brother. Which of the following best explains the amount of ice cream left in Grant's bowl?

 

Options to pick below! 

 

(A) 2/6, because 2/3-2*(1/6)=2/3-3/6,

(B) 2/6 because  2/3-2*(1/6)=2/3-2/6,

(C) 1/6 because 2/3-2*(1/6)=2/3-3/6,

(D) 1/6 because 2/3-2*(1/6)=2/3-2/6   

 

Please help Thankyou!

2/3 - 2 (1/6) = 2/3 - 2/6

                    = 4/6 - 2/6 = 2/6 = 1/3

You want to make both denomiator's in this problem the same, So you have: \(\frac{2}{3} - \frac{2}{6} = ?\)We can find the LCM

 

(Least common mulitple) of these numbers, which is 6 because 6*1 = 6 and 3*2 = 6 So now we know we have \(\frac{2}{6}\)but we need to change \(\frac{2}{3}\) to a denomiator of 6, we

 

can do this by simply changing it to six and to find the numerator we divde 6 by 3 and then multiply the quotient by the numerator of 2/3 which is to

 

so 2*2 is equal to 4 so now we have \(\frac{4}{6}-\frac{2}{6}=\frac{2}{6}\) 

 

 

So now we know \(\frac{2}{6}\) is or answer. whic reduces to \(\frac{1}{3}\)
