Question

how to divide decimals fractions

Answer 1

100, 1000 etc. are discussed here.

(i) While dividing a decimal by 10, 100, or 1000 etc. i.e., multiples of 10, the decimal shiftsto the left by as many places as there are zeroes in the divisor.

(ii) If the number of places in the integral part is less, then put the required number ofzeroes to the left of the integral part, then shift the decimal point.

1. 71.6 ÷ 10

Solution:

71.6 ÷ 10

716/10 ÷ 10

= 716/10 × 1/10

= 716/100

= 71.6 ÷10

= 7.16

Therefore, 71.6 ÷ 10 = 7.16

Here we observe that decimal moves one place to the left.

Step 1: Estimate the answer by rounding.

Step 2: If the divisor is not a whole number, then move the decimal place n places to the right to make it a whole number.

Step 3: Divide as usual.

Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.
