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 Jul 25, 2019

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 $$\frac{1}{3}$$

Well I'm leaving this in your judgemnet to figure that part out. we have presented how to solve for the solution.
