Answer all I mark him brainiest if you answer only one I just give you thanks and step by step explanation
(a) Is 80136 divisible by 11(solve it)?
(b) Renu purchases two bags of fertilizer of weights 75 kg and 69 kg. Find the
maximum value of weight which can measure the weight of the fertilizer exact
number of times.
Answers
Answer:
a)Is 80136 divisible by 11? Difference of the two sums = 15 – 3 = 12, which is neither 0 nor the multiple of 11. Hence, 80136 is not divisible by 11.
b)
Weight of the first fertilizer bag = 75 kgs
Weight of the second fertilizer bag = 69 kgs
The H.C.F of 5 and 69 is the highest weight that can evaluate the exact number of times of the fertilizer.
Highest Common Factor or HCF is the largest common divisor or gcd of two or more positive integers, as the mathematics rules dictate, appears to be the largest positive integer that divides the numbers without leaving a remainder.
For finding maximum weight, we have to find H.C.F. of 75 and 69.
Factors of 75 = 3 x 5 x 5
Factors of 69 = 3 x 23
H.C.F of 69 and 75 is 3
Hence, the maximum weight value is 3 kg, which can calculate the same number of times the weight of the fertilizer.
