Answer:

1 1/2 hours

Other ways to show would be; = 1 1/2 hours = 1 .5 hrs = 90 minutes

Step-by-step explanation:

We write out the question 2 1/4 - 3/4 = ?

Then you use the model A below

Next you can add on from the smaller number 3/4 being step 1

And you use model B to find step 2 + step 3 as it reminds you that there is 1/4 in total time being the smallest box out of the sum.

step 1 = 3/4 + 1/4 = 1 = 1/4 is missing in A model box

step 2 = + 1 (to make 2) = 1 is left in B model box

step 3 is + 1/4 is left in B model box

Then add the up = 1/4 + 1 + 1/4 = 1 1/2

Your answers will be model represents 3hrs divided into 6 hours

Brody sliced a small pizza into 12 equal pieces. He ate ~ of the pizza. Which model represents three-fourths of twelve?

EastWind [94]

Answer:

Pie chart.

9 slices

Step-by-step explanation:

Three-fourths of twelve is written as

3/4 * 12

i.e 3/4 is multiplied by 12

multiplying 3 by 12 gives 36 and dividing it by 4 gives 9 .

So Brody ate 9 slices out of the 12 slices of pizza.

The graph used in circular shape is called the a pie chart.

If we draw a pie chart 3 of the 4 sections will be colored showing that he ate 3/4 of the pizza representing 9 slices out of 12.

Each slice can be represented separately.

How do you graph an inequality on the number line if they are the same number? Using "and"

Korvikt [17]

If the sign looks like > or <, it excludes the number, if there is a line under the < or >, it is inclusive, which means at least, or at most. To display inclusive draw a circle on the point and fill it in, for exclusive, draw a circle and don't fill it in.
