Blababa [14]

<u>Question</u>:

Ted and Robin each gave a basket of green apples to their friend Lily. Ted’s basket contains 5 apples, each weighing 7 1/4 ounces. Robin’s basket contains 6 apples, each weighing 6 1/2 ounces. Whose basket is heavier and by how much?

<u>Answer</u>:

Robin’s basket is heavier than Ted’s basket  by  2.75 ounces

<u>Step-by-step explanation:</u>

<u>Given</u>:

Ted’s basket contains  = 5 apples

Weight of each apple in Ted’s basket = 7 1/4 ounces

Robin’s basket contains  = 6 apples

Weight of each apple in Robin’s basket =  6 1/2 ounces

<u>To Find:</u>

Whose basket is heavier and by how much?

<u>Solution:</u>

<u>Step 1: Finding the weight of Ted’s basket </u>

Weight of Ted’s basket  = Number of apple in the basket X  Weight of each apple

Weight of Ted’s basket  = 5 \times 7\frac{1}{4}

Weight of Ted’s basket  = 5 \times \frac{29}{4}

Weight of Ted’s basket  = \frac{145}{4}

Weight of Ted’s basket  =  36.25 --------------------------------(1)

<u>Step 2: Finding the weight of Robin’s basket </u>

Weight of Robin’s basket  = Number of apple in the basket X  Weight of each apple

Weight of Robin’s basket  = 6 \times 6\frac{1}{2}

Weight of Robin’s basket  = 6 \times \frac{13}{2}

Weight of Robin’s basket  = \frac{78}{2}

Weight of Robin’s basket  = 39 ounces--------------------------(2)

<u>Comparing equation (1) and (2)</u>

39 - 36.25 = 2.75 ounces

Weight of Robin’s basket  >  Weight of Ted’s basket

How to write3.repeating 7 as a mixed number
ki77a [65]

Hey there! I'm happy to help!

Let's call our fraction x.

x=3.777......

We want to get rid of the repeating stuff. If we multiply our fraction by 10, we get 10x=37.7777.

We see that if we subtract x from 10x, the repeating numbers will be cancelled out. Let's do this.

10x=37.7777

-

x=3.77777

=

9x=34

We divide both sides by 9.

x=34/9=3 7/9.

Have a wonderful day! :D
