Sorry, I’m busy but I’ll help you with this one.

100% - 15% = 85%

$555 / 100 = $5.55

$5.55 x 85 = $471.75

3/7÷1/2 how do you graph this

Luda [366]

3/7 divided 1/2 is the same as 3/7 times 2 which is 6/7.

Not sure what you mean by graphing it though. Like on a number line? There is no x or y in your equation.

Adriel answered 54 questions correctly on his multiple choice history final and earned a grade of 45%. How many total questions

alex41 [277]

Answer:

There were 120 questions on the test.

Step-by-step explanation:

It is given that:

Number of questions answered = 54

Grade percent = 45%

Let,

x be the total number of questions

45% of x = 54

$\frac{45}{100}x=54\\0.45x = 54$

Dividing both sides by 0.45

$\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120$

Therefore,

There were 120 questions on the test.

How can you multiply 5 x 2/12

Nikitich [7]

Answer:

12 1/2

Step-by-step explanation:

Hi Glenishagreaves!

The easiest way to begin is to convert 2 $\frac{1}{2}$ to an improper fraction.

2 × 2 = 4 + 1 = 5.

So 2 $\frac{1}{2}$ = $\frac{5}{2}$

5 × $\frac{5}{2}$ = $\frac{25}{2}$

Converting to a mixed number gives a final answer of $\boxed{12 \frac{1}{2} }$$ .
