Question

Write each of the following as decimals:
1) Seven-tenths
2) Two tens and nine-tenths
3) Fourteen point six
4) Two hundred and two ones
5) Six hundred point eight

Answer 1

Hint: We will first consider all the given values and we have to convert them in decimal form. We will first write the given expression in numerical form and then convert it into the decimal form. The expressions which have ‘and’ in them, use addition in that. The term ‘point’ refers to the decimal in the given expression.

Complete step-by-step answer:
1) In this the expression is seven-tenths, we will first convert the value in the numerical form.
Thus, the numerical form is \[\dfrac{7}{{10}}\]
Now, we will convert this numerical form into decimal form,
Thus, we get,
\[ \Rightarrow \dfrac{7}{{10}} = 0.7\]
Hence, the seven-tenths can be written as \[0.7\].

2) In this the expression is two tens and nine-tenths, we will first convert the value in the numerical form.
Thus, the numerical form is \[2 \times 10 + \dfrac{9}{{10}}\]
Now, we will convert this numerical form into decimal form,
Thus, we get,
\[ \Rightarrow 20 + \dfrac{9}{{10}} = 20 + 0.9 = 20.9\]
Hence, the two tens and nine-tenths can be written as \[20.9\].

3) In this the expression is fourteen point six, we already have value in the decimal form.
Thus, the required decimal form is \[14.6\]
Hence, the fourteen point six can be written as \[14.6\].

4) In this the expression is two hundred and two ones, we will first convert the value in the numerical form.
Thus, the numerical form is \[2 \times 100 + 2 \times 1\]
Now, we will convert this numerical form into decimal form,
Thus, we get,
\[ \Rightarrow 200 + 2 = 202\]
There is no decimal in this expression.
Hence, the two hundred and two ones can be written as \[202\].
5) In this, the expression is six hundred points eight, we already have value in the decimal form.
Thus, the required decimal form is \[600.8\]
Hence, the six hundred point eight can be written as \[600.8\].

Note: We have converted the given expression in decimal form by converting it into the numerical form. Wherever tens are used, it means to multiply the number by 10 and wherever hundreds are used, multiply the number by 100. Tenths refers that divide the number by 10.
