Question

Daniel goes for painting class every day for 35 minutes. How many hours does he learn painting in a month?

Answer 1

Hint: Here, we need to find the number of hours Daniel learns painting in a month. We need to use the concept of multiplication to get the required number of hours he learns painting in a month. Multiplication is the repeated addition of equal groups.

Complete step-by-step answer:
Multiplication is the repeated addition of equal groups. It helps in adding multiple equal groups quickly. It is denoted by the symbol \[ \times \]. Brackets may also be used to denote multiplication.
For example: Suppose that the number 2 is added repeatedly 15 times, that is \[2 + 2 + \ldots \ldots + 2\] 15 times. This can be represented using multiplication as \[2 \times 15\].
Now, it is given that the time spent by Daniel to learn painting in 1 day is 35 minutes.
It is assumed that the month has 30 days.
We can multiply the time spent in 1 day by any number \[x\], to get the time spent by Daniel in \[x\] days.
Multiplying the time spent in 1 day by 30, we can find the time spent to learn painting by Daniel in 30 days.
Therefore, we get
Time spent to learn painting by Daniel in 30 days \[ = 35 \times 30\] minutes
Simplifying the expression, we get
Time spent to learn painting by Daniel in 30 days \[ = 1050\] minutes
Therefore, Daniel spends 1050 minutes a month learning painting.
Now, we will convert 1050 minutes to hours.
We will use a unitary method to convert 35 minutes to degrees.
We know that 1 hour is equal to 60 minutes.
Therefore, we get
60 minutes \[ = \] 1 hour
Dividing both sides by 60, we get
\[ \Rightarrow \] 1 minute \[ = \dfrac{1}{{60}}\] hours
Multiplying both sides by 1050, we get
\[ \Rightarrow \]1050 minutes \[ = \dfrac{{1050}}{{60}}\] hours
Simplifying the expression, we get
\[ \Rightarrow \]1050 minutes \[ = 17.5\] hours
Therefore, the number of hours Daniel spends in a month to learn painting is \[17.5\] hours.

Note: We used a unitary method to convert 1050 minutes to hours. Unitary method is a method where first, the per unit quantity is calculated, and then the number of units are multiplied. Here, we first calculated the value of 1 minute in hours, and then multiplied it by 1050 to get the value of 1050 in hours.
