Question

EXERCISE 1.4
1. Without actually performing the long division, state whether the following rational
numbers will have a terminating decimal expansion or a non-terminating repeating decimal
expansion:35/50​

Answer 1

Answer:

yes, it is a terminating decimal because the denominator is in the form of 2^n.5^m

Answer 2

Answer:

it will have terminating decimal expansion

Step-by-step explanation:

for terminating decimal expansion we have to get 2^n × 5^n

here,

35/50, we get 7/10 after dividing it by 5

in 7/10, 10= 2×5 which is terminating bcz. 2×1 × 5×1 is the outcoming answer. as here n is 1 for both 2 nd 5.

so it is terminating expansion
