For example: Lets say you are buys a pair of shoes for $20. It's on sale for 30% off. Put a decimal in front of the amount of the discount .30 And then multiple .30 by the amount it is originally 20 Your answer will be 6. Subtract $6 from $20 and that is how much your pair of shows will be with the discount. Answer: $14

How do you ungroup a 3 digit number? My nephew is working on his homework and I have no clue how to help him.

Talja [164]

In monetary terms, you're making change. If you need more ones, you trade one 10 for 10 ones.

When I was in school, many years ago, we used small superscript-type numbers to show this:

7 3 0 ⇒ 7 2 ¹0 . . . . regrouping to gain 10 ones

7 2 ¹0 ⇒ 6 ¹2 ¹0 . . .regrouping again to gain 10 more tens

You'd have to look at the example problems that precede this page in order to see what the meaning of "magnifying glass" is.

In preperation for an easter egg hunt, 4 blue eggs are filled for every 7 green. How many green eggs will be filled if 100 blue

ivann1987 [24]

Answer:

1. Typed question: 175 green eggs

2. Attached: 22 tables

Step-by-step explanation:

For the question you typed down, it is a ratio and proportion problem. You need to solve for the ratio proportional to the first ratio given.

4 blue eggs are filled for every 7 green. This means that the ratio between blue eggs and green eggs is 4:7.

Now yo need to figure out a ratio proportional to 4:7 if 100 blue eggs were filled. Below is how this is set up:

$\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}$

Now let's solve for x:

$\dfrac{4\;blue\;eggs}{7\;green\;eggs} = \dfrac{100\;blue\;eggs}{x\;green\;eggs}\\\\or\\\\\dfrac{4}{7}=\dfrac{100}{x}\\\\Cross-multiply\\\\4x = (7)(100)\\\\4x = 700\\\\Divide\;both\;sides\;by\;4\\\\\dfrac{4x}{4}=\dfrac{700}{4}\\\\x=175$

For your attached problem:

You have a total of 175 people, you need to figure out how many round tables you need if here are 8 chairs for each table You just need to divide the number of people by the number of chairs per table.

175 ÷ 8 = 21.9 tables

Now since you cannot have half a table, you round up to the nearest whole number. (we round up because you need to make sure that all of them are seated)

21.9 ≅ 22 tables.
