Pls help .[1] Solve the eguation 4*=28. [2] change 1/20 to decimal [3] change 60% to a common fraction . Pls i need the solving thank you
1) 4x = 28
4 times what number = 28?
2) 4/20
Divide the numerator by the denominator
3) 60% = 60/100 = 6/10 = 3/5
1 / 20 = 5 / ( 5 * 20 ) = 5 / 100 = 0.05
60% = 60 / 100 = 3 * 20 / ( 5 * 20 ) = 3 / 5
What 4*=28 mean ?
2=5
Sure! I'd be happy to help you with these problems.
[1] Solving the equation 4x = 28:
To solve for x, we need to isolate the variable on one side of the equation. In this case, we have 4x = 28. To isolate x, we can divide both sides of the equation by 4:
4x/4 = 28/4
Simplifying, we get:
x = 7
Therefore, the solution to the equation 4x = 28 is x = 7.
[2] Converting 1/20 to a decimal:
To convert a fraction to a decimal, we simply divide the numerator (the number on top) by the denominator (the number on the bottom). In this case, we have 1/20:
1 ÷ 20 = 0.05
Therefore, 1/20 as a decimal is 0.05.
[3] Converting 60% to a common fraction:
To convert a percentage to a common fraction, we divide the given percentage by 100 and simplify if possible. In this case, we have 60%:
60% ÷ 100 = 0.6
We can simplify this fraction by dividing both the numerator and the denominator by 10:
0.6 ÷ 0.1 = 6/10
Finally, we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2 in this case:
6/10 ÷ 2/2 = 3/5
Therefore, 60% as a common fraction is 3/5.
I hope this helps! Let me know if you have any further questions.
