The HCF of 1.75, 5.6 and 7 is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 0.35.
Convert all numbers to fractions or remove decimals
1.75 = 175/100
5.6 = 560/100
7 = 700/100
Now all numbers have the same denominator (100), so = 175, 560, 700
HCF of 175, 560, and 700 ⇒ 5 × 7 = 35
So, HCF of numerators = 35
HCF of fractions = 35 / 100 = 0.35
