**Subtract.**

Question 1.

a.

Answer:

When the numbers have a different number of decimal places, they are termed as, unlike decimal fractions. In this case, we count the number of digits after the decimal point in both numbers and identify the higher one in these. Then, we add the required number of zeros to the smaller decimal number to make it the same length as the other number. After this, we subtract the decimals numbers.

Therefore, the difference is 71.1

b.

Answer:

Subtracting decimals with the same number of decimal places is simple. We just need to do the simple process of subtraction and then place the decimal points according to the given numbers.

Therefore, the difference is 30.2
