Harriet has 3/4 tank of gas left in her car. if she needs 1/4 tank to go to her friends house and another 1/4 tank to get back home,does she have enough gas? explain your answer

Answers

Harriet has enoughgas to make the trip to her friend's house and back without needing to refuel her car.

What is Fraction?

A fraction represents a part of a whole.

Given that Harriet has 3/4 tank of gas left in her car.

She needs 1/4 tank to go to her friends house and another 1/4 tank to get back home.

We need to check whether she has enough gas for her trip.

Since Harriet has 3/4 of a tank of gas left, she has 1/4 of a tank already used.

She needs another 1/4 of a tank to go to her friend's house and another 1/4 of a tank to get back home.

Altogether, she needs 1/4 + 1/4 = 1/2 of a tank for the round trip.

Hence, Harriet has enoughgas to make the trip to her friend's house and back without needing to refuel her car.

Ok so if you add the two 1/4's you will find how much gas she needs total to complete the trip. So do 1/4 + 1/4 and get 1/2. Next you can see that 3/4 is larger than 1/2, so she has enough gas.
Hope that helps!

Explain and demonstrate how to change 4/20 into a percent

Answers

4/20 is equivalent to 20%.

What is a expression? What is a mathematical equation?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
A mathematical equation is used to equate two expressions.
A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correctanalysis, observations and results of the given problem.

We have the following fraction -

4/20

We can convert it into percent as -

[x]% = (4/20) x 100

[x]% = 20%

Therefore, 4/20 is equivalent to 20%.

You can start by dividing both top and bottom by four, making it 1/5. From there you can do 1 divided by 5 making it a decimal of 0.2. Afterwards, move the decimal to places to the right and add an extra 0 making the percentage 20%.

How do i do precent to fraction

Answers

To change a fraction to a percent, treat it like a division problem. For example, to make 1/4 a percent, divide the numerator by the denominator. 1 ÷ 4 = 0.25.

Next, move the decimal point two places to the right. That changed 0.25 to 25, and just add the percent symbol. 25%

AND BAM! You've got yourself a fraction changed to a percent. 1/4 = 25%

You need to remember that "percent" and " % " both mean " / 100 " .

When you see, let's say, "35 percent" or "35 %", it means " 35 / 100 ".

Bam ! There's your fraction. If it can be simplified, and if you
feel like it, you can go ahead and simplify it.

35 / 100 = 7 / 20 .
