Question

what can be the greatest weight that can be used a number of times to weight 54 kg and 72 kg of rice ?​

Answer 1

Answer:

9kg

Step-by-step explanation:

We can simply find out the hcf (or gcd) of 54 and 72 which is 9. Therefore the greatest weight that can be used a number of times to weight 54 kg and 72 kg of rice is 9kg.

Answer 2

This requires the highest common factor of 54 and 72.

First split into prime factors: 54 = 2*(3^3)

72=(2^3)*(3^2)

Multiply together common prime factors: 2*3*3 = 18

18 is the HCF of 54 and 72.

Therefore, greatest weight is 18.

Hope this helps!
