You are making necklaces for your friends. you have 36 blue beads and 42 red beads. how many necklaces can you make? show your work .

In a question like this, you are trying to find the Highest Common Denominator, or HCF. This can be done manually, by finding all the factors of 42 (1,2,3,6,7,14,21,42), all the factors of 72 (1,2,3,4,6,8,9,12,18,24,36,72), and comparing them to see that their HCF is 6. Or, it can be done by dividing both numbers,

=7242, simplifying the fraction

=127, then dividing the starting number with the new simplifiied number, remembering always to divide numerator with numerator and denominator with denominator.

7212=6 or 427=6

This process works with any two numbers which you want to find the HCF of, and can be simplified into this rule:

If a= any number, b= any number and cd is the simplified fraction of ab,

The HCF =ac or =bd

I hope that helped!

thanx

same question

different concept

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88

you never say the total so we cant find the percentage used for petrol
