She has $30=20% of the total price so basically add 80% to 30. The total amount the skateboard costs is $150.00 she still needs $120.00 more

When converting units, summarize the steps using the Direct Method .
STALIN [3.7K]
Steps are simple:
1- Write the standards of conversion
2- Write the value you want to convert
3- Use cross multiplication to get the converted value

Examples:
i- Say we want to convert 890 cm to meters.
We know that 1 cm = 0.01 meters
Now, we will write the number we want to convert and use cross multiplication as follows:
1 cm     = 0.01 meters
890 cm = ?? meters
converted value = (890*0.01) / 1 = 8.9 meters

ii- Say we want to convert 568 kg to grams.
We know that 1 kg = 1000 grams
Now, we will write the number we want to convert and use cross multiplication as follows:
1 kg     = 1000 gram
568 kg = ?? grams
converted value = (568*1000) / 1 = 568000 grams

Hope this helps :)

Find two numbers between 1.4142133 and 1.41422
Naddik [55]

Hey there! I'm happy to help!

To find the number halfway between two numbers, you simply add them and then divide by two.

1.4142133+1.41422=2.8284333

2.8284333/2=1.41421665

That is one number in between these two. Now, we can find the number in between the middle number and the second number. This is another number in between our two numbers.

(1.41421665+1.41422)/2=1.414218325

You could keep on doing this and find tons of numbers in between these two.

Therefore, two numbers between 1.4142133 and 1.41422 are 1.41421665 and 1.414218325.

Have a wonderful day! :D
