Audrey's parents give her $5 to play video games at the mall.Each games costs a quarter to play.which choice is NOT a correct me
thod for determining the total #of games she can play. A.Take the #of dollars she has and divide it by 1/4. B.Take the # of dollars she has and multiply it by 4. C.Take the # of dollars she has and divide it by 0.25. D.Take the # of dollars she has and multiply by 0.25
If answer A works then so will Answer A. The reason is because 1/4 and 0.25 are equal to one another. The only comment you should recognize is that
5/0.25 is a whole lot easier to do than 5/(1/4)
B is the same thing as C when you apply the division by fractions rule.
D is the odd method out. Instead of 20 games (5 * 4) she will only get to play 4. That because she has 5 dollars and if you multiply by 0.25 you get 1.25 games
D. take the number of dollars she has and multiply by .25.
dividing by a number is the same as multiplying by it's reciprocal. since she is dividing by .25, she needs to multiply by the reciprocal (4,) but instead, she is just multiplying by .25.
