Lisa spent $67 for a skateboard and $25 for a protective helmet.What percent of the total amount that Lisa spent was the price of the skateboard? Round to the nearest tenth of a percent, if necessary.

A.
62.7%

B.
72.8%

C.
75%

D.
81.7%

Answers

percent means out of 100 so
x%=x/100
Lisa spent 67 and 25
what percent was price of skateboard

so percent of total price
total price=skateboard+helmet=67+25=92
total(skateboard and helmet)=92

then percent out of 100
67 out of 92=67/92
one way is to divide fully and get
0.728261/1
make denomentator 100
multiply by 100/100
72.8261/100=72.8261%

the answer is about 72.8%

the answer is B

3 3/4 Divided by 2 1/12

Answers

The required answer would be a fraction of 9/5 which is determined by 3 3/4 Divided by 2 1/12.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

To determine the evaluation of 3 3/4 Divided by 2 1/12

⇒ 3 3/4 ÷ 2 1/12

Convert the mixed fractions into the Improper fraction, we get

⇒ 15/4 ÷ 25/12

Apply the Division operation, and we get

⇒ (15/4) / (25/12)

Reciprocal the terms of the denominator

⇒ (15/4) × (12/25)

⇒ 180/100

⇒ 18/10

⇒ 9/5

Therefore, the required evaluation of 3 3/4 Divided by 2 1/12 would be a fraction of 9/5.

#SPJ2

First make the fractions into improper fractions.
So then it becomes
15/4 divided by 25/12.
Next do the KCF method (Keep.change. Flip)
Keep 15/4 the same and switch the numbers of 25 and twelve. Then multiply.
15/4 x 12/25= 180/100
Simplify.
So 3 3/4 divided by 2 1/12 =9/5
9/5 can also be written as 1 4/5

What is the answer snd steps to 4/5=-4/7g

Answers

$(4)/(5)= (-4)/(7g)\ \ \ \Rightarrow\ \ \ 4\cdot7g=5\cdot(-4)\ /:(4\cdot7)\n \ng= (5\cdot(-4))/(4\cdot7) = -(5)/(7) \n\n------------\n\n (4)/(5)= (-4)/(7)\cdot g\ /\cdot (- (7)/(4) )\n \n g=(4)/(5)\cdot (- (7)/(4) )=- (7)/(5)$

Isolate the variable g on one side of the equation by multiplying by (-7/4) on each side. The fours cancel since you get (4/5)*(-7/4) = (4/4)*(-7/5) = 1*(-7/5) and you're left with g = (-7/5) = -1 2/5 = -1.40

How to rewrite decimals to fractions before adding

Answers

Step 1: Write down the decimal divided by 1, like this: decimal/1Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)Step 3: Simplify (or reduce) the fraction . ( Did That Help ? )

fraction divide e.g. 7/20 is 7 divide by 20 equals 0.35.
in decimals you times it by 100
e.g. 0.35 x 100 equals 35%

and if your trying to find the fraction all yoju do is do the oposite
