Steps to solve:

6 * 4 + 2 / 2 - 7

~Multiply

24 + 2 / 2 - 7

~Divide

24 + 1 - 7

~Add

25 - 7

~Subtract

In step one, she added instead of multiplied which caused her to get the wrong answer.

Best of Luck!

Hey there! I'm happy to help!

Step 2 is incorrect. She added 4 and 2 first, but you are supposed to multiply and divide first. Then she multiplied 6 and 6, which is 36. Then she divided 36 and 2, which is 18, and then she subtracted 7, giving her 11. Step 2 is what threw the whole thing off.

Here is what Sandy should have done.

STEP 1: 6·4+2÷2-7

STEP 2: 24+1-7

STEP 3: 25-7

STEP 4: 18

I hope that this helps! Have a wonderful day! :D

Fabian is taking out a loan in the amount of $10,000. His choices for the loan are a 4-year loan at 4% simple interest and a 6-y

erica [24]

Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

Considering the first choice,

P = $10000

R = 4%

T = 4 years

I = (10000 × 4 × 4)/100 = $1600

Considering the second choice,

P = $10000

R = 5%

T = 6 years

I = (10000 × 5 × 6)/100 = $3000

the difference in the amount of interest that Fabian would have to pay for each of these two loans is

3000 - 1600

= $1400

Of the student in mr. smiths fifth grade class, 1/3 were absent on Monday. Of the students in mrs Jacobs class 2/5 were absent o

antoniya [11.8K]

There are 12 students in Mr. Smith's class and 10 students in Mrs. Jacob's class.

<h3>Further explanation</h3>

<u>Given:</u>

Of the student in Mr. Smith's fifth grade class, $\frac{1}{3}$ were absent on Monday.
Of the students in Mrs. Jacob's class, $\frac{2}{5}$ were absent on Monday.

There were 4 students absent in each class on Monday.

<u>Question:</u>

How many students are in each class?

<u>The Process:</u>

<u>Part-1:</u> in Mr. Smith's class

The diagram representing all students in the class is as follows:

$\boxed{\cdot} \boxed{\cdot} \boxed{\cdot}$

$\frac{1}{3}$ were absent on Monday, that is $\boxed{\cdot}$ or 1 of 3 units.

There were 4 students absent on Monday.

Let us count how many students are in Mr. Smith's class.

$\boxed{ \ 1 \ unit = 4 \ students \ }$

$\boxed{ \ 3 \ unit = \ ? \ students \ }$

$\boxed{ \ 3 \times 4 = 12 \ students \ }$

Thus, there are 12 students in Mr. Smith's class.

<u>Part-2:</u> in Mrs. Jacob's class

The diagram representing all students in the class is as follows:

$\boxed{\cdot} \boxed{\cdot} \boxed{\cdot} \boxed{\cdot} \boxed{\cdot}$

$\frac{2}{5}$ were absent on Monday, that is $\boxed{\cdot} \boxed{\cdot}$ or 2 of 5 units.

There were 4 students absent on Monday.

$\boxed{ \ 2 \ unit = 4 \ students \ }$

$\boxed{ \ 1 \ unit = \ ? \ students \ }$

$\boxed{ \ 4 \div 2 = 2 \ }$

Therefore, $\boxed{ \ 1 \ unit = 2 \ students \ }$

Let us count how many students are in Mrs. Jacob's class.

$\boxed{ \ 1 \ unit = 2 \ students \ }$

$\boxed{ \ 5 \ unit = \ ? \ students \ }$

$\boxed{ \ 5 \times 2 = 10 \ students \ }$

Thus, there are 10 students in Mrs. Jacob's class.

- - - - - - - - - -

<u>Conclusion</u>

There are 12 students in Mr. Smith's class.
There are 10 students in Mrs. Jacob's class.
