Answer:
The number of required shelves is 5
You have to find the HCF of 45, 105, and 75.
First you do -13+9. That equals -4.
Then bring down -c=-4 because there is a 1 in front of the c so -1c.
Next divide both sides by -1. The -c side cancels out so then your left with -4/-1.
That equals positive 4.
C=4
That’s ur answer.
23/50 is 0.46 so the percentage would be 46%
