Number lines are used to represent numbers and ratios using regular intervals
Nuka can weave 8.75 cm of strip in 5 minutes
<h3>How to determine the length of strip</h3>
Represent the ratio with:
Ratio = Length : Time
From the number line, they can weave 7cm of the strip in 4 minutes.
So, we have:
Ratio = 7cm : 4 minutes
Represent the length of strip made in 5 minutes with x.
So, we have:
x : 5 minutes = 7cm : 4 minutes
Remove the common units
x : 5 = 7cm : 4
Express as fraction
Multiply both sides by 5
Evaluate the quotient and the product
Hence, Nuka can weave 8.75 cm of strip in 5 minutes

Answer: your answer is C. there is no common factor between 6 and 15.
Answer:
1020 raisins
Step-by-step explanation:
Let's set up a proportion using the following setup:
raisins/bags= raisins/ bags
We know there are 680 raisins in 8 bags.
680 raisins/8 bags= raisins/bags
We don't know how many raisins are in 12 bags, so we can say x raisins are in 12 bags.
680 raisins/ 8 bags= x raisins / 12 bags
680/8=x/12
We want to find x. To do this, we must get x by itself.
x is being diveded by 12. The inverse of division is multiplication. Multiply both sides of the equation by 12.
12*(680/8)= (x/12)*12
12*680/8=x
12*85=x
1020=x
x= 1020 raisins
There are 1020 raisins in 12 bags.
