Answers
Answer:
Decimals into Fractions
(i) 7025/1000
(ii) 9595/100
Step-by-step explanation:
(1) Find the GCD (or HCF) of numerator and
denominator
numerator = 7025
denominator = 1000
GCD of 7025 and 1000 is 25
Divide both the numerator and denominator by
the GCD
7025 ÷ 25 = 281
1000 ÷ 25 = 40
Putting numerator and denominator into
reduced fraction: 281/40
Therefore, 7025/1000 simplified to lowest terms is 281/40.
Hence, 7.025 = 281/40
(2) Find the GCD (or HCF) of numerator and
denominator
numerator = 9595
denominator = 100
GCD of 9595 and 100 is 5.
Divide both the numerator and denominator by
the GCD
9595 ÷ 5 = 1919
100 ÷ 5 = 20
Putting numerator and denominator into
reduced fraction: 1919/20
Therefore, 9595/100 simplified to lowest terms is 1919/20.
Hence, 95.95 = 1919/20
