It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of the whole. It has two parts: the numerator (number on the top), here 42, represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 50. A decimal is a way to represent a number that is not whole, using a (.) or a decimal point to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
42/50 in decimals can be written as 0.84. It is a terminating decimal, meaning it does not repeat infinitely.
To convert 42/50 to a decimal, we will use the division method. Since 42 is smaller than 50, we will use the decimal method, which will give us 0.84. Let's break down the process step by step:
Step 1: Identify the numerator and denominator because the numerator (42) will be taken as the dividend and the denominator (50) will be taken as the divisor.
Step 2: As 42 is smaller than 50, it can't be divided as a whole number. We will add a decimal point and a zero to the dividend, making it 420.
Step 3: Now, we can divide 420 by 50. Let's see how many times 50 fits into 420.
Step 4: 50 goes into 420 eight times (50 × 8 = 400). We will write 8 in the quotient place and subtract 400 from 420, which gives us 20.
Step 5: Bring down another 0 to the dividend place, making it 200. Repeat the division process: 50 goes into 200 four times (50 × 4 = 200).
Step 6: Subtract 200 from 200, resulting in a remainder of 0. Since there is no remainder, the division ends here.
The answer for 42/50 as a decimal is 0.84.
