What is the highest common factor (HCF) of the fractions 3/16, 5/12, and 7/8?
Explanation
To find the HCF of fractions, determine the HCF of the numerators and the LCM of the denominators. The numerators are 3, 5, and 7, whose HCF is 1. The denominators are 16, 12, and 8, with an LCM of 48. Therefore, the HCF of the fractions is 1/48.
