On thursday Bernies dog ate 1/4 lb more dog food than she ate on wednesday. On wednesday, the dog ate 1 1/3 times the amount of

kirill115 [55]

"On Thursday Bernie's dog ate 1/4 lb more dog food than she ate on Wednesday."

That means that on Wednesday, the dog ate 1/4 lb LESS that it ate on Thursday.

"On Wednesday, the dog ate 1 1/3 times the amount of food she ate on Tuesday."

That means that on Tuesday, the dog ate 1 1/3 times LESS that it ate on Wednesday.

Now start with Thursday: "If Bernie's dog ate 1 3/4 lb food on Thursday"

On Wednesday it ate 1/4 lb less that that, so on Wednesday it ate

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

On Wednesday it ate 1 1/2 lb.

On Tuesday it ate 1 1/3 times less than on Wednesday. Now we divide 1 1/2 by 1 1/3.

$= 1 \dfrac{1}{2} \div 1 \dfrac{1}{3}$

$= \dfrac{3}{2} \div \dfrac{4}{3}$

$= \dfrac{3}{2} \times \dfrac{3}{4}$

$= \dfrac{3 \times 3}{2 \times 4}$

$= \dfrac{9}{8}$

$= 1 \dfrac{1}{8}$

Answer: It ate 1 1/8 lb of food on Tuesday.

Bryson buys a bag of 64 plastic miniature dinosaurs . could he distribute them equally into six storage containers and not have

MariettaO [177]

Okay so first you would ask your self does 64 divide by 6? So take out your calculator and divided 64 by 6. Doing so you find out the answer is 10.6 (repeating)
So each storage container would get 10? No that doesn't sound right, instead you have to turn the repeating 6 into a fraction so it would be each storage container gets 10 2/3 of a dinosaur.
