Hi there!
If any term, no matter what the number multiplied by zero will always turn out to be zero. I can give you an example of why this is correct.
We'll use apples. :P
If we have four apples multiplied by zero, you'd have zero apple because there's NO groups of apples to use.
Two times three is six because there are two groups of three, or three groups of two. But since earlier we said that there were zero groups of apples, there is zero groups of four so that cancels out to make none.
Hope this helps! :D
Answer:
the unit rate of 1/7 is itself (1/7), and for 1/21 is 1/21.
Step-by-step explanation:
this is because these rates/ratios are unit fractions. so if the numerater is 1, theres nothing you can do to simplify it.
you can check with the ceaser method as well, but you're still going to find the same solution.
plus, for example, if it takes 7 grams of sugar to make 1 cake, it wouldnt make sense for 1 gram of sugar to make 7 cakes.
hope this helped clear up your confusion <3
