Hint: To convert a percent into a decimal, we will have to convert it into a fraction first. For converting it into a fraction, we will divide the percent by . If the percent is a whole number, we will just simplify the fraction. But if the percent is not a whole number (as is the case here), we will multiply both the numerator and denominator with followed by as many zeroes as there are numbers after the decimal point in the percent. After converting it, we will turn the fraction obtained into an equivalent fraction which has , , or followed by as the denominator. Then, we will just write down the numerator, putting the decimal point at the correct place. The correct place is one space from the right-hand side for every zero in the denominator.
Complete step by step solution:
Given percent is .
Now, we will divide by , such that
Since is not a whole number, therefore we will multiply both the numerator and denominator with as there is only one digit after the decimal point. Therefore, the fraction becomes
Since the fraction already has in the denominator, we will just convert it into a decimal by writing down the numerator and putting the decimal point at the correct place. Here, the correct place will be spaces from the right-hand side of , as there are zeroes in the denominator. Therefore we will get,
Hence, can be written in decimal form as .
Note:
can be converted into a decimal by an alternate method also. After converting into a fraction, we have got . After simplifying this fraction into its simplest form, we will get . Now to convert into a decimal, we can perform the long division method.
Complete step by step solution:
Given percent is
Now, we will divide
Since
Since the fraction already has
Hence,
