lorasvet [3.4K]

Answer:14 children are expected to be at the museum

Step-by-step explanation:

Let x represent the total number of adult and children in the museum.

Ratio of adults to children at a museum is usually 5:2. The total ratio would be the sum of the proportions of adults and children. It becomes

5 + 2 = 7

There are currently 35 adults at the museum. It means that

5/7 × x = 35

5x/7 = 35

5x = 7 × 35 = 245

x = 245/5 = 49

The total number of adults and children in the museum is 49

The number of children in the museum would be

49 - 35 = 14

Ilia_Sergeevich [38]

In unit form: 5 ones thousands 5 hundreds
In standard form: 5,500

<h3>Further explanation:</h3>

Problem: (5 hundreds 5 tens) x 10

Question: what is the result in unit and standard form

This is a problem with place value. In standard form, 5 hundreds 5 tens are 550.

Let's do the multiplication first.

Hence,

$\boxed{ \ = (5 \ hundreds \ 5 \ tens) \times 10} \ }$
$\boxed{ \ = 550 \times 10} \ }$
$\boxed{\boxed{ \ = 5,500} \ }}$

Now consider the result. Let's write the result in unit form and standard form.

In unit form: 5 ones thousands 5 hundreds
In standard form: 5,500

Remember these

A standard form ⇒ is written in number form
Unit form ⇒ writing a number using place value units

Another example

What is (5 hundreds 5 ones) x 10 in the unit and standard form?

In standard form, 5 hundreds 5 ones is 505.

Hence,

$\boxed{ \ = (5 \ hundreds \ 5 \ ones) \times 10} \ }$
$\boxed{ \ = 505 \times 10} \ }$
$\boxed{\boxed{ \ = 5,050} \ }}$

Let's write the result in unit form and standard form.

In unit form: 5 ones thousands 5 tens
In standard form: 5,050
