Question

Find the hcf and LCM of 1.75,7.6 and 7

Answer 1

Answer:

Answer is 0.35

Step-by-step explanation:

1.75 = 175/100 = 7/4

5.6 = 56/10 = 28/5

7 = 7/1

In general for any two fractions a/b and c/d where a, b, c, d are integers and b,d != 0 then gcd( a/b, c/d ) = gcd( a, c ) / lcm ( b, d ).

Therefore gcd( 7/4, 28/5, 7/1 ) = gcd( 7,28,7 ) /lcm( 4,5,1) = 7/20 = 0.35
