:)find the value of the following​

Answer 1

Answer:

(i) 2.35, 2.53, 5.32, 3.52, 3.25 Comparing the whole number parts of all the numbers 5 is the greatest and 5 > 3 > 2. ∴ Greatest number is 5.32 Next 3.52 and 3.25 are equal in their whole number. So comparing their digits in tenths place, we get 5 > 2 So 3.52 > 3.25 Now comparing 2.35 and 2.53 their whole number parts also equal. ∴ Comparing the digit in tenths place we get 2.53 > 2.35 … (2) Ascending order : 2.35 < 2.53 < 3.25 < 3.52 < 5.32 (ii) 123.45, 123.54, 125.43, 125.34, 125.3 Comparing the whole number parts we have 123 is the smallest number and two numbers 123.45 and 123.54 have same whole number part. So in 123.45 and 123.54 comparing their digits in the tenths place we get 4 < 5 ∴ 123.45 < 123.54 … (1) Now comparing the remaining numbers 125.43, 125.34, 125.3 they all have the same whole number part. Comparing the numbers in the tenths place we have 3 < 4 ∴ 125.43 is the greatest … (2) Also tenths place value 3 = 3 in 125.34 and 125.3 Again comparing the hundredths place value in 125.34 and 125.3, we get 125.3 < 125.34 …(3) From (1), (2) and (3) we have, 123.45 < 123.54 < 125.3 < 125.34 < 125.43Read more on Sarthaks.com - https://www.sarthaks.com/994654/arrange-the-following-in-ascending-order-2-35-2-53-5-32-3-52-3-25-ii-123-45-123-54-125-43-125-34-125
