For this case we must find the value of n of the following equation:
Taking common factor "n" from the left side of the equation we have:
Multiplying by 5 on both sides of the equation:
Dividing between 6 on both sides of the equation:
Thus, the value of n is 20.
Answer:
In this case, we have 2 proportional rectangles. That means the ratio of their <span>width:length</span> will be same. The bigger rectangle length 20 cm and width is 5cm. Then to find the smaller rectangle width, you need to multiply the smaller rectangle length with width:length ratio. The ratio would be:
width:length ratio= bigger rectangle width/ bigger rectangle length= 5cm/20cm= 1/4
Then the smaller rectangle width is 8cm * 1/4= 2cm
To turn a fraction into a decimal, you have to divide the numerator by the denominator.
So, divide 7 by 16 and you get 0.4375
The decimal is 0.4375.
Hope it helps
If you want to turn a fraction to a decimal, you have to divide the numerator by the denominator in order to get a decimal number. If the fraction is a mixed number, you would do the same but make sure that the whole number is in front of the decimal.
